My old early 2008 Macbook Pro appears to be making its curtain call with what appears to be a logic board problem (freezing randomly from any startup disk) and so I am looking for a replacement. I've had my eye on a little 11 inch Macbook Air for a while and was wondering if a top specced machine (2ghz 8mb 256/512mb) would be enough to deal with my work. I like the idea of its portability as I travel quite a lot and need to regularly update my websites. For photography work I would hook it up to a big display, mouse/tablet and keyboard. I use Lightroom and CS suite mostly Photoshop. I use a 5DII and an Hasselblad H3DII-39 so my files can get pretty big. I know ideally I should have a Mac Pro or high spec iMac workhorse and that is the plan in maybe 12 months but for now this would be my main computer. I hadn't planned on upgrading this soon and don't really have the budget for both right now. Does this sound realistic or should I have a re-think? I am assuming that a 2012 Macbook Air would have at least as much go as my MBP (2.6ghz core 2 duo, 6gb ram, SSD startup/software drive and HD files drive).
