First, I would LOVE to have a PowerBook, but they're just too expensive. So please don't try to tempt me with it. Second, a 12" screen is kinda cramped, a little small for watching DVDs, and all that. So I've narrowed things down to the 14" iBook. And now to my question. Is it really worth spending $150 for the extra 67MHz? I won't be doing too much processor-intensive stuff, just web-surfing, a little Photoshop maybe, some web-dev, some gaming, etc. Any thoughs to help me make up my mind would be greatly appreciated!
