I've had my mind set on the 27" i5, but the more I think about it, the less I'm sure I need it. Here are my basic needs: iphoto imovie garageband some basic photoshop work pixelmator, etc rapidweaver web office...etc. no gaming at all. So, what do you folks think?...all I know is that anything will be better than the iBook G4 (10.4) I'm currently using. I'm just wondering if tacking on an extra 700ish bucks is worth it over the 21" i3 or i5. How much futureproofing does the 27" get me? Is it worth it? Clearly (as can be seen from my G4), I have a habit of hanging on to my gadgets far too long. What are the other (maybe not-so-obvious) perks of bumping up to the 27"? Thanks.
