Asus crams Windows 8 and Android 4.1 into one gargantuan tablet

PC World - The general population might best know Asus for its work on Google's Nexus 7 tablet, but hardcore tech enthusiasts know the Taiwanese company for all its inspired--some may zany--reinterpretations of common computer formfactors. Next in the list of Asus flights of fancy? An all-in-one desktop/tablet combo that doesn't make you choose between Team Windows and Team Android.

Asus Transformer AiO

At first blush, the Transformer All-in-One P1801 looks like a relatively ordinary all-in-one PC, except for one clear distinction: The 18.4-inch display is mounted in a docking shelf.

When you turn it on, this all-in-one's unique approach becomes more evident. The unit runs both Windows 8 and Android 4.1 Jelly Bean, an unusual dual-operating system combination; you can switch between the two OSes by tapping a button along the right edge of the tablet. The switch is seamless, and makes hopping between Windows and Android viable. Previously, the largest Android tablet we've seen was Toshiba's Excite 13, at 13 inches.

The Transformer All-in-One's split personality extends beyond its dual-OSes. It also has two processors, another unique find: The docking station contains an Intel Core i5 or i7 processor, while the tablet itself also contains Nvidia's Tegra 3 processor.

Pricing starts at $1299 for the Core i5 version with a 1TB hard drive in the base station and 32GB of EMMC solid-state storage in the tablet. Asus plans to start shipping its PC-tablet combo sometime in the first quarter of 2013.

When disconnected from the base, the tablet portion weighs 5.73 pounds--certainly not something you're going to carry about nonchalantly. But somehow, when I held it, the well-balanced unit felt neither unwieldy nor bulky. That might have been due in part to the fact that the display has a convenient pull-out handle that makes it easy to remove. It also has its own built-in stand if you prefer to prop it up directly on a table surface for giving a presentation or watching movies. The tablet portion could come in handy for playing tabletop games and other tabletop-style group apps yet to come.

The 18.4-inch LED-backlit, IPS display supports 10-point multitouch and 1920 by 1080 pixel resolution. My one gripe with it is that it has one of the largest air gaps between the glass and the LCD beneath I've seen in a while. (A large air gap between the screen and its glass covering can increase glare and reduce the display's perceived clarity.)

You can use the tablet on Windows 8 while it's connected wirelessly to a PC base station; however, when you exceed the Wi-Fi range (the range has yet to be finalized) it will switch to being an Android tablet. The base station packs a ton of connectivity, including four USB 3.0 ports.
