I've owned the 11.6" MBA for a couple of months now and it works great. It's portability is fantastic because I have to take it with me to several locations where I don't have a lot of work space. It's fast and the battery life is decent enough so that during the day I really don't require a power cord (but I don't go online much with it during the workday). The only time I see it slow down a little is when I'm accessing my Yahoo email in Outlook.
