Hello there! Unless in the next few hours I have a complete change of heart - I have decided to go with the MacBook Air over the 13" Pro. I'm not on the move all of the time, but I do tend to use my computer off-desk. Never owned a Pro but it's obviously not going to be as nice on lap as an Air. My needs are pretty average, but, I do have the manic tendency to want to go top of the line (this feeling is enhanced with the limited upgrade-ability of the Air!)! I also have no real need for an optical drive, and the increased resolution is just a bonus. Anyway... The machine is going to be my only system. With that in mind, I can't come to a decision over which model to choose! I've pretty much set my mind on the 13" - but which variant? Ha, as if I can decide! I don't do video work and only light photo editing, but I do have a decent sized music collection. At this stage I'm unsure of whether I intend to keep the machine for years to come, or upgrade while I still have a decent resale value. I'm split between the 128 and 256 SSDs - with it not being easily user replaceable I'm more or less stuck with what I go for. Of course, by not having the 256 SSD I can't go all out and choose the i7... I wish I was more decisive!
