Apologies for yet another MBA 13 vs. MBP 2011 13 thread, but... I need a new computer: the elderly hamsters that power my 2006 Dell XPS M140 are finally dying. I've long since become a Mac fan thanks to my wife's iMac, and I need a small-ish laptop for general use and commuting. (I have a VERY long commute on Metro-North, and I want to carry my computer with me nearly every day). Typical uses: Word, internet, managing moderate photo and music libraries (with external storage at some point), and some InDesign. I think I would be a perfect candidate for the MBA 13 except for lack of Firewire, which I use at work, though not a lot. I'm also skittish about not being able to upgrade it. My gut tells me to get the entry-level 2011 MBP 13, which I can get at a 10% discount through my employer, and upgrade to 8GB RAM for a little snap and "future-proofing." I can then upgrade to a SSD if/when it becomes necessary. The screen resolution doesn't bother me that much; god knows it will blow away the Dell. And to be honest, I've compared the MBA 13 and the MBP 2010 in the stores several times and the weight differential didn't seem that dramatic. Anyway, many thanks for the advice.
