Own a maxed 2010 13" MBA, it's been a flawless machine. Don't know if it's worth the trouble to upgrade to the latest MBAs. A backlit keyboard is nice, but I'm wondering if it makes sense to move up from a perfectly capable 2010 machine that works great and is arguably the best laptop I've ever owned. Another issue is the sprinkling of issues with these new MBAs, including this LG v. Samsung screen, instant-on seems to be not-so-instant when resuming from Lion, and some other things. Anyone waiting until Lion SP1 is released to make a decision, or make the jump to a new MBA 13"?
