I may be in the market for a MBA, as a second machine but I'm not sure what a good price is. I've seen them as low as 800 bucks and as high as 1700. While ebay isn't a good indicator (the 1.6Ghz 80gig for 1700 is over priced) I'm not sure what is a good price. Also revision As seem to have a reputation of overheating, is it worth spending 800 (or more) for one, especially given its anemic GPU or should I just save up for a Rev B? Thoughts, opinions and suggestions on the MBA would be greatly appreciated. I currently own a MBP, that typically sits on my desk, plugged in to my monitor, ext drive, keyboard, printer etc. So its a little bit of a hassle to unplug everything when I just want to use it for some light work on my lap say in the living room. Plus having a second smaller mac for when I do travel could be a plus. I'm also interested in perhaps using ubuntu on this either as via bootcamp/VMware. Not sure of that complicates matters at all.
