Not a tablet itself, the MMT Monitor2Go is a multi-touch, 15.6 LED display that you can carry around as a second screen to your tablet. The company calls the 3-lb Monitor2Go perfect for business presentations, and I can see that. Both are connected via HDMI or USB, and have a slot to insert an iPad 2 or 3. The $299 model has 1366x768 resolution. I'd pay $30 more for the 1600x900 version.
Maybe Japanese engineers have gotten tired with miniaturizing gadgets, because here is the 2nd tablet-like device greater than 20-inches coming from the island. The maker is Frontier, and the product is the 21.5-inch, 11 lb. Frontier FT103. The FT103 runs Android 4.0 ICS, and the resolution is 1920x1080. But the rest of the specs are lackluster - 1 GHz dual-core ARM chip, 8 GB flash storage. And unlike the Sony VAIO Tap 20, there doesn't seem to be a battery. Hmm, maybe it is, as the makers call it, just a "SmartDisplay." The Frontier costs just US$440, which is good, since you'll need that money to pay for your flight to Japan to buy it, and all of the chiropractic work afterwards.
Another high-end Windows 8 tab-laptop, the Iconia Tab W700 has a 11.6-inch screen with a 1920x1080 display, Intel Core i5 1.7 GHz chip, 128 GB SSD, 8 hours of battery life, Dolby Home Theater sound and Micro HDMI and USB 3.0 ports. That configuration will cost $999. A Core i3-based version will be $200 less.
