I'm looking to buy a new MBP in the coming days (waiting to see if a new upgrade is announced). In the meantime, I'm doing my homework. Trying to decide how worth it the 200G 7200rpm upgrade is for the Hard Drive. Obviously, in an ideal world, the faster, slightly bigger HD wins. But I have no real need for the extra space (I have all the space I need with 160G + external storage) and I don't really use my computer for high-performance stuff (gaming, rendering, or whatever). Is the improvement in performance/speed that obvious between 5400 and 7200? I mean, is it something noticeable on "standard" applications? (Anything from GarageBand to basic iTunes, mp3 ripping, etc.).
