Just tried one out
Just tried one in the local Currys. Not great. In contrast to my AC100, the build quality seems relatively poor: nasty plastic flap over the ports, spongy power button. The LCD's viewing angle is the same as the AC100 and much worse than the iPad, and it is also much more fingerprint-prone than the iPad. At least it is not a resistive screen, and people should be satisfied with the processor and graphics performance thanks to the Tegra processor.
Android works better on this than on the AC100, of course, but there's still no Google market and it's still far from easy to use - it took another customer to show me how to unlock the screen.
After the Currys visit, though, I fear that the worst problem may be the sales channel. A few doors down there is an Apple store which is always full of teenagers poking their facebooks and playing silly games on the dozens of iPads, iPods and iPhones. Currys had precisely one of these tablets, without any sort of window display or supporting marketing material - and with no WiFi. So even if a potential customer were able to get beyond the screen lock, they'd not be able to do any facebook poking. "But if we had wifi, we'd have the shop full of teenagers poking their facebooks!" said the employee when I commented on this. "Precisely! They are called Customers!", I replied. He seemed to think that they were going to sell lots anyway. He might be right, but in the 1.5 days they have had these (and the Galaxy tab) in stock, they had sold NONE; the first was sold while I was there to an ARM employee.
The Galaxy Tab, BTW, was a much better experience - mainly thanks to a much nicer screen - but you would hope so too, at that price.
