I am starting a new project which requires frequent air travel between the same two cities. I am fortunate enough to have a 17" (mid 2007) MBP at home and a brand spanking new i7 15" MBP at the other site. I really do not want to lug a MBP on/off the plane anymore and would like an ultra for traveling (mostly). I do not expect the AIR to do any heavy lifting, but would like to use it for some media (e.g. video), e-booking and iWork. Also, I really need it for Keynote presentations. I really do not want another egg-fryer (already have two of those ), and it has to have decent battery life. I was thinking of a refurbed 2.13GHz AIR with a SSD... I know an AIR update MAY be imminent, but for my needs I do not have to have the latest and greatest. Does the current 2.13 AIR fit the bill, especially wrt over-heating? P.S. - Not really considering the iPad for now.
