As I look at case options for my SPro, I find the selection quite lacking. Microsoft, Amazon, Ebay, Taobao, and Etsy seem to all just offer endless variations on the same old sleeve. So, for more selection (and maybe better pricing), I thought we could together figure out what other devices (tablets or laptops) are about the same size. For starters, I think the MacBook Air 11-inch is just slightly larger. Does anyone have a side-by-side picture?
