Ultimate mobile deathmatch

The latest Android 2.0-based "iPhone killer" won't kill theiPhone or the BlackBerry -- and the cheaper HTC Droid Eris is the new smartphone that I think Apple should be concerned about. But there are now six smartphones on the market that will appeal to business and professional users, each with different strengths and weaknesses. This article gives InfoWorld's ratings for all six -- the Apple iPhone, HTC Droid Eris, Motorola Droid, Palm Pre, Research in Motion BlackBerry Bold, and RIM BlackBerry Storm 2 -- plus an interactive ratings form in which you can enter your own weighting for each category in our exclusive Mobile Deathmatch Calculatorand get a customized score for each smartphone.

Our buying advice is simple:

* If you want a mobile device that takes full advantage of Web connectivity, applications, and personal media that you can also use for business connectivity such as e-mail and calendaring, get the iPhone, even with the inferiority of AT&T's 3G network.

* If you're subject to high security requirements, such as for regulatory compliance, need to manage lots of devices, or just can't handle using a touch-based screen keyboard, you want the BlackBerry Bold, which is available from several U.S. carriers.

* If you can't stand the thought of using the AT&T 3G network and don't need to access corporate e-mail (outside of POP and IMAP mail servers), you want the HTC Droid Eris, which, like the Motorola Droid, is available only from Verizon Wireless.

The WebOS-based Palm Pre was innovative last spring but has been bested by the new generation of Android devices. (Its sole U.S. carrier, Sprint, appears to have moved on from the Pre, now focusing on Android devices.) The Motorola Droid's keyboard is unusable, and its lack of a multitouch screen makes its few technical advantages over the HTC Droid Eris -- basically, a few extra security features -- a lousy bargain. The BlackBerry Storm 2 was supposed to fix an unusable clickable touchscreen in the original version, but the solution doesn't address the core issue: Tapping is very slow on the screen, to the point that sustained text entry is out of the question. It's not surprising that within weeks of its release, carriers are selling it as part of two-for-one specials.

Windows Mobile and Nokia Symbiandevices are also out of the picture. Microsoft's long-delayed Windows 7 Mobile remains vaporware, and making purchase decisions on Microsoft's promise is foolhardy. Nokia's Symbian OS has evolved slowly in the last decade and simply isn't in the same league as modern mobile OSes; Nokia knows that and has a plan to move -- over several years -- to a new OS called Maemo. Someday we'll see what Maemo has to offer; in the meantime, Nokia has been unable to get U.S. carriers to sell its smartphones.

Web and Internet support

One of the iPhone's revolutionary advances was in bringing the Web to mobile devices in a capable, effective way. All of a sudden, the mobile Web was real. The WebKit browser that underlies the iPhone's Web experience is now used by the Palm Pre and Android devices, and it seems destined for BlackBerry. For now, however, the BlackBerry series are the only holdouts for the old, hard-to-use mobile Web. The BlackBerry OS's ability to reformat Web pages into a stack helps overcome some of its inability to deal with real Web pages, but it's no substitute for the real thing. The Motorola Droid's lack of multitouch support makes navigating Web pages awkward; furthermore, the Droid's multistep process to copy text and the inability to copy graphics fall short of the iPhone's standards.

Likewise, the ability to access Internet services like Facebook, search, YouTube, and so on (another area iPhone pioneered) is pretty much standard across all modern mobile devices today. The same is true for JavaScript support, though this capability is turned off on many BlackBerry models by default and must be activated by the user. Some carriers disable JavaScript support completely.

The one common Web technology in which the iPhone OS is at a disadvantage is Flash Player support -- it doesn't have it. Neither do the Droids. The other devices can display Flash video. All but the BlackBerrys can display QuickTime Video, though there's a third-party app that lets the BlackBerry view QuickTime videos.

Business connectivity

Where stark differences between the current mobile contenders show is in support for corporate e-mail, calendars, and contacts. The BlackBerry, if you use the extra-cost BlackBerry Enterprise Server, lets you access these services whether your business uses Microsoft Exchange, IBM's Lotus Notes, or Novell Groupwise. It's the most enterprise-capable mobile platform for business connectivity.

The iPhone is second-best for business connectivity. It supports Exchange ActiveSync for e-mail, calendars, and contacts, though there are no clients as yet for Notes or Groupwise. The iPhone OS 3.1 fixes a bug that falsely reported support for ActiveSync on-device encryption policies; the 3G S supports such encryption, but older iPhones do not and thus can't access Exchange if encryption is set as an ActiveSync policy requirement.

The Palm Pre claims to support Exchange, but it supports only a few ActiveSync policies and thus can access only low-security Exchange servers. The two Droids also claim Exchange support, but I could not get the HTC Droid Eris to connect at all, while the Motorola Droid could only send messages, not receive them, a common complaint on the Droid user forums as well. The likely culpritis lack of support for ActiveSync policies. (My colleague Paul Venezia was able to establish a connection between a Droid Eris and an Exchange server that had no ActiveSync policies enabled.)

Note that Verizon enforces an extra $15-per-month fee to access corporate e-mail; if you don't tell Verizon you're using Exchange and don't call tech support for help on using Exchange, you can probably avoid the fee. But given the poor Exchange compatibility, it's pretty much a moot issue. The Motorola Droid does work with Exchange calendars through ActiveSync, but it won't let you respond to invitations.

All six devices support POP and IMAP e-mail accounts, so they're fine for personal and small-business e-mail access. They all support Google's Gmail as well, though BlackBerry owners will want to download RIM's "enhanced" Gmail client. To sync the iPhone to your PC's e-mail and calendar (as opposed to an Exchange server), you have to use either iTunes or the $99-per-year MobileMe service. The two Droids will directly sync to Outlook calendars and e-mails over a USB connection, as well as via Google Apps. BlackBerrys also can sync to Outlook on your PC, and to iCal and Address Book on your Mac, via a USB cable, using the BlackBerry Desktop software.

Application support

Two billion downloads and counting -- that pretty much says it all about the wealth of available iPhone apps. No device comes anywhere close to the iPhone regarding the variety of third-party apps, and Apple keeps enhancing what apps can do, such as by enabling in-app purchases and subscriptions this summer.

The Google Android Market is looking good in its early days, with several high-quality programs available that match the better iPhone apps' quality, though often with fewer capabilities than their iPhone equivalents. HTC loads the Droid Eris with more than a dozen cool widgets that work only with its Sense UI enhancements to the Android OS; these bring real sophistication to the Droid Eris. Examples include a weather-and-time widget for the home screen, an integrated console for accessing all your messages, a favorites quick-access widget for contacting people with one click, and a mail-preview widget that means you don't have to keep opening the Email app.

Apps for the Pre have largely stalled, though the early ones showed promise. The BlackBerry has the weakest selection of apps, many of which are ungainly and hard to use, reflecting the platform's lack of respect for usability.

The BlackBerry does support unzipping of zipped file attachments in e-mail, unlike the other devices. The iPhone supports viewing of more document types than any of the devices, by dint of supporting its iWork productivity apps in addition to Microsoft Office and PDF documents. The two Droids and the BlackBerrys require that you use a third-party app to view such documents, but they come with this software pre-installed (Quickoffice for Android and Documents to Go for BlackBerry, respectively). The Pre, like the iPhone, comes with its own app for file viewing.

In some -- but not all -- cases, these viewers can also edit documents. Further, editing capabilities can be quite limited. For editing documents, DataViz Documents to Go for BlackBerry is the easiest to use, as it works with e-mail attachments and zip files. The Quickoffice app for the iPhone is a better editor, but it work only with files stored on the iPhone, not directly with e-mail attachments, due to an Apple-imposed limitation. However, Quickoffice for Android is more limited still -- it only supports document viewing. The sole editing app for the Android platform, Documents to Go, can merely edit e-mail attachments in Gmail messages.

The iPhone's copy and paste is the best of the bunch; it's intuitive and works on all sorts of content in almost every app. The BlackBerry's copy-and-paste capabilities are comparable to the iPhone's, but the menu-based interface is harder to use. The Palm Pre and the two Droids have limited copy-and-paste capabilities.

The Motorola Droid boasts an included turn-by-turn navigation app that doesn't require a monthly subscription, unlike the other devices. You can buy such apps for the iPhone and BlackBerry, for between $80 and $130.

All six devices offer the basics when it comes to apps: e-mail, calendar, address book, social networking, test messaging, maps, media player, and photo gallery.

The Palm Pre and HTC Droid Eris go a bit further than the others in their communications-oriented apps in letting you easily manage your contacts across communciations channels. You can even have a conversation that moves from one channel to another with the Pre. Only the Pre makes it easy to move among apps when you have several running, thanks to its "cards" interface.

Security and management

Although security and management concerns can be used as an excuse not to deal with something new, the truth is that companies subject to regulatory requirements -- such as hospitals, defense contractors, and financial officers -- have to follow those requirements. If those needs apply to you, no other device capabilities can trump security, and that means you're all but certain to choose a BlackBerry. The BlackBerry Enterprise Server (BES) can track and enforce security policies, such as requiring that data stored on the device be encrypted, and it can initiate a remote wipe of a device after a specified number of failed password attempts, for example. Plus, BES can push security, policy, and app updates, as well as monitor device usage.

The iPhone comes in second place for security and manageability, despite its poor reputation. It supports Exchange ActiveSync policies, such as requiring a complex password or on-device encryption. The iPhone 3G S and the late-2009 iPod Touch support on-device encryption, a common security requirement. The iPhone offers more security capabilities than are initially apparent, because many policies can only be set through Apple's iPhone Configuration Utility, a free download. The utility creates policies that iPhone users can install via e-mail, URLs, and USB syncing -- but there's no way to force, confirm, or track installation, so many enterprises can't prove security compliance without physically checking each device.

The Pre, Droid, and Droid Eris have limited security capabilities (the Pre has the most and the Droid Eris the least) and no management tools. Companies that offer mobile management tools are increasingly adding iPhone and Android support, but the scope of these tools remains less than regulation-concerned enterprises require.

The BlackBerrys, iPhone, Pre, and Motorola Droid all support VPN connections; only the HTC Droid Eris doesn't. The BlackBerry's support is superior, as its VPN settings can be remotedly managed by IT. Using the free iPhone Configuration Utility, IT can also send iPhone users VPN profiles to install, but can't remotely manage them.
