I've read plenty of posts about whether or not the air is for me, and I think it fits my needs perfectly. My question is do I really need the SSD? My situation is I would be using it purely when I travel. Web surfing, itunes, and movies off of an external HD. So do I need to fork out the extra cash for the SSD? Also, given what I will be using it for, would it benefit me at all if I went the the Macbook Pro? I honestly don't mind the extra weight, but a new MBP vs a refurb Rev B w/ 120 HD are very similar in price. And if no big difference for what I need, then I might as well go with the air. I'm not a huge computer guy, but is it correct when saying that playing movies off an external HD it won't matter which type of computer you are using? it only matters how good the external HD is? Thanks!!
