I'm patiently awaiting(yeah right) my 2.2 MBP. I'm still considering switching the order to a Macbook because the difference might not be that big..but probably not. One of the things I was going back and forth about at the time of ordering was upgrading from the standard 120GB to the 160GB 7200 rpm HDD. I really wanted the 7200, but I thought it would take longer, and I wasn't sure if I needed it. I suppose I could still change my order, but I really need it by a certain day this month, because I'm going on a long trip. There's still a chance I might not even get it by then, so I don't want to prolong it any longer than I need to. Anyway, what I'm wondering is; is it worth it and is it possible to bring it to an Apple retail store and get it upgraded to that very 7200 model? I don't want to voice my warranty doing it on my own , and I'd just feel more comfortable knowing Apple was doing it. I doubt I'm going to use all of the space, but extra space is always good. And apparently the 7200 RPM helps a bit? I'm planning on using as my primary computer for the next few years at least, so I figure it's worth it. Am I right? Thanks.
