I'd say go for it. I was the exact same way with my 3650 and my 3950. I didn't bring them with me because they were too big. Especially now on campus with wifi, that would require carrying a sleeve and a card.

So I got a 2215. Much smaller, easier to carry. Even that is a pain though because then I have to carry the card. Even that is a pain for me now.

4150 looks just about perfect, at least for me, in size and feature set. Very small, and built-in wifi. No CF slot needed anymore, just my SD card for mem backup.
