I've got a 10" MSI win7 tablet that's got a piddling little 1.0GHz dual core, 2Gb RAM and a 32Gb SSD. It's not as smooth to use for media as my wife's iPad, and the 16:10 aspect means it's not as well-balanced, either, and its battery only keeps up for 4.5-5 hours, although I've got a 66Wh pocketable (theoretically. It pulls my trousers down, so it's really fanny packable or courier satchelable) backup charger. But it's capable of running desktop apps while being lugged on-site, and I've been using it with TurboCAD. That's been frustrating because TC's UI isn't great for touch-screens. I'd tried Autodesk's 123D on the tab too, with mixed results. The navigation cube is good with a touch UI, but it's a real-time direct edit app, with a 2GHz recommended minimum, so with a 1GHz CPU, real time is real sloooow.
Now I've transferred Shark V7 on to the tab, and what a revelation! I don't use it with a mouse, but the Navigator is exactly the right thing for touch, roll-out-and-tear-off toolbars are SO fluid, and, at least with the relatively lightweight files I've been using, it's all happening pretty crisply. If I can get this tab to hear Keith K's speech recognition macros, it'll rock harder yet.
Kudos, Tim. This interface really is a natural for tablets. You iOS guys don't know what you're missing out on - apart from Flash.
