Yes, I know there are many of these threads already, but anyway... Tomorrow (6-30-07) I'm going to replace my BlackBook with a MBP from a brick 'n' mortar Apple store. I have enough to afford the HD 17" although my original idea was to get the top 15" (both glossy if possible, not sure about the HD 17"). Any thoughts on this? Oh, and just so you know, it won't leave my desk very often, but will occasionally, but I love every last drop of power (15 min more for a 15" than a 17" isn't that big a deal). But isn't the GPU a little more taxed in the 17" because of the screen size and will there be a noticeable performance hit because of it? Also, is there any sort of advantage to the 17" (aside from that extra USB port, I don't think so anymore). I'm leaning towards the 15", but if you can convince me otherwise...
