Seven things to consider for a Windows tablet

IDG News Service - Come Oct. 26, when Microsoft is set to stage a release party in New York City, consumers may have to choose between a tablet with Windows 8 or Windows RT. The operating systems look and feel the same, but devices will differ on performance, price, battery life, usage and application support.

Windows RT is Microsoft's first OS for ARM processors, which are found in Apple's iPad and most Android tablets. Analysts say RT is targeted at consumers and will attract a new generation of users with little ties to PCs, much like the iPad. The OS will come preinstalled on tablets and differ in some ways from Windows 8, which is considered a successor to previous Windows operating systems.

"People should play with them in the store to see if the device is right for them," said Dean McCarron, principal analyst at Mercury Research. "We have a new device class, a new architecture, and people need to figure out how it fits with their device usage model."

Here are some things to consider when looking at RT tablets:

Windows RT or 8?

Microsoft has engineered Windows RT for touch, Internet connectivity and long battery life, and some tablets highlight those features. Windows RT is viewed as more of a tablet OS in the mold of Apple's iOS, while Windows 8 tablets may appeal to PC users looking for backward application compatibility. The cheapest RT tablet is Microsoft's Surface, which starts at $499, while Asus' Vivo Tab RT starts at $599.99. Windows 8 tablets are competitive on price, with Acer's new W510 tablet priced at $499 with an Intel Atom chip code-named Clover Trail.

Application compatibility

With a few exceptions, existing Windows applications will not work on RT. That is partly because ARM processors have not supported major desktop Windows client OSes in the past. But existing applications will work on Windows 8, as previous Windows OSes over the past few decades were written primarily for Intel or Advanced Micro Devices processors. Microsoft is adopting a new application model with Windows RT and 8, and users will be able to download applications through Microsoft's application store, which will show up as a tile in the user interface. "I think that Windows' new app store is ... a move from Microsoft to catch up with the changing distribution channels for software," said Nathalie Lussier, a technology consultant in Brooklyn, New York, who is looking into Windows hardware.

Peripherals and accessory compatibility with Windows RT

A lack of drivers may prevent some older peripherals such as printers or cameras from working with RT. Some device drivers may not have been written to work with RT -- an issue that's similar to existing Windows applications not working with RT. It may be worth checking with device makers to see whether they have drivers for RT. Dell and Hewlett-Packard have published lists of printers that will and won't work with RT.
