I usually use my Mac Air with an external keyboard & monitor. When I stop work, I just let it go to sleep mode. When I come back, I get error messages over the Finder window for Firefox, MS Office and Thunderbird, programs I usually leave open. This can be a real pain if I haven't gotten around to saving my work or left in the middle of writing a long email.
The problem isn't all the time. The Air came with Lion.
