If there is a Guinness Book of World Records entry for Largest Tablet, the Sony VAIO Tap20 would be it. This is basically an all-in-one Windows 8 PC with a 20-inch, 1600x900 capacitive 10-point multitouch screen. But...it actually has a built-in battery with an alleged life of 3.5 hours. At its size (140 sq. inches, 11.4 pounds), you'll probably only lug it around your home or office, setting it up in flat or reclining mode (with the rear kickstand). Specs are full PC-like, with your choice of Intel Core i3 to i7 processors, 8 GB RAM and up to 1 TB hard drive space. Alas, you pay for what you get, with a Japan price of between $1,800 to $2,300.
While we dream of a possible Samsung P10 (2650x1600 resolution) tablet, there are two pretty worthy options available today: the Series 5 and Series 7 tablets. Both are 11.6-inch tablets. The mid-range Series 5 has the Intel Atom Clover Trail processor and 9 hour battery life, while the Series 7 has a Core i5 and 5-6 hour battery life. Both support pen input, ala the Galaxy Note. Unlike other Windows 8 lap-tablets, the $100 keyboards are strictly optional. The Series 5 starts at $649, while the Series 7 starts at $1,119.
You might have already been considering the Toshiba Excite 13 tablet - it was released earlier this summer. It's a 13.3-inch (1600x900) Android 4.0 ICS tablet with an Nvidia Tegra 3 chipset that tips the scales at 2.2 pounds. The $650 price for the 32 GB version looked high compared to the similar-but-smaller $199 Google Nexus. Reviews were thus mixed. But I think the Excite 13 looks very reasonable today to anyone who doesn't need Windows 8 or a keyboard.
