Yes, it can run Windows.
But, of course, the neat gestural/multitouch touchpad doesn’t work under Windows. The best you can get there is two buttons plus scroll control. Too bad.
I assumed it ran Windows, which is why I made my joking speculation. But if the touchpad doesn’t work under Windows, that’s actually a pretty big downside - although I recognize it’s not a downside to the faithful, who’d never deign to run Windows. It would be kind of a pain to those on the fence or not fully converted to buy an ultra-compact laptop and then have to carry a USB mouse around with them to be able to use Windows.
As I said, I’m just being complimentary on what looks like a neat piece of technology. I’m not about to buy one or anything, so the touchpad doesn’t actually concern me.
