An Asus x202e "Vivobook". A couple of years old.If you don't mind me asking, what Windows laptop are you using that is 11.6"?
Nothing fancy in terms of specs, especially compared to an MBA. A Core i3, 4GB RAM, 500GB HDD. But I prefer Windows, and it has a touchscreen so I can get the most out of Windows 8.1, and it only cost $499. It gets the job done. Decent build quality too. Not as thin as the MBA, but mostly metal except the bottom which is some kind of rubber.
I really hope that there are still good 11" Windows laptops on the market when I'm ready to replace it.
