I've been using an black 13" MacBook for a while now, and I find that it fits comfortably in my lap when sitting in a chair and when sitting with my legs crossed Indian style. However, given it's age and, more so, the fact that it's pretty heavy to travel with, I'm looking at buying an 11" MacBook Air to replace the MacBook. I was wondering if anyone would share me with their experiences with using an 11" MBA in your lap. Is it comfortable? How does it compare to a 13" MacBook or MacBook Pro? Do you find that keyboard fits your hands nicely? I'm a 6'3" guy, and I weight around 180 pounds (188 cm/82 kg). So if anyone with a similar body type has had experience using an 11" MBA on their lap, I'd appreciate some insight. I went to an Apple store to play around, but because the Macs were chained down, I couldn't get a great feel for it. Thanks!
