Hahaha, are you serious. Emulate a computer with a full keyboard, mouse, and joystick, on a touch screen? Tablets and smartphones suck bad enough for emulating simple game consoles (it's one of the chief complaints I hear even from my tablet-evangelist coworkers.) It's not like there's something magical about Ivy Bridge that's going to make it more usable than it is on Android.
Using Workbench emulated with Winuae with a touch screen could be cool.
I agree with the touch controls for games that were not designed for it.
Floating d-pads & buttons are really horrible. Speedball II at the iPhone is kind-of-cool, but...
Absolutely nothing related with Windows vs Android.
and, for your information, I don't even like Laptops! I'm a desktop guy: Big Box, Big Monitors, Large Keyboard, Mouse and etc...
...But I can see myself using that surface over iPads. Never considered an Android tablet.
I have my Desktop and several laptops to play with different operating systems.
For productivity, nothing beats Windows.
