Well, Linux and OS X wake-from-sleep times have always been pretty good but these laptops will usually be compared to Windows laptops, and the Windows wake-from-sleep is a stuttering mess in comparison.

I can easily use my MacBook Air on my lap. Actually that is one of the key reasons I bought it--better LAPtop computing experience. My MacBook was heavy enough that it became uncomfortable to use for more than an hour or so at a time, and it would also get hot enough under load that it became uncomfortable. And actually once it had warmed up for a while it was a little too warm for me. So the MacBook Air is light enough and cool enough that I enjoy using it on my lap for hours at a time. I don't know why you can't seem to keep yours from shaking around while using it. Might want to consult your doctor about that.
