Appreciated.
The thing is, I've never experienced a Mac before, so I'm still leaning on owners' impressions to guide me through.
I own a pretty decent desktop rig: i7 920, 3GB RAM, 8800GT @ 512MB, OCZ Vertex 2 SSD 60GB, running W7 Ultimate. The most hardcore thing I ever did with it was some random gaming (played Crysis 2 on very high @ 1920x1080 i.e. just to try it out; it ran fine), but as I stated before, I am NOT a gamer, so rolling out gaming from the "What I want my Macbook to do list" is perfectly fine.
As in the problems I had with the Vostro, I definitely want a clean & smooth machine, on which I don't need to worry about drivers and viruses and the registry getting corrupted and BSODs and weird errors popping up, lock ups and system faults. I really want it to be super stable and rock solid.
As for activities, I will mainly stick to the usual: browsing, YouTube (basically everything else browser-related), watching some 1080p movies (locally), music (and some casual DJ-ing), documents for University, Photoshop, printing and probably some lightweight video edit once or twice. Oh yeah, and probably some HTML, if I ever want to resume my learning sessions.
Good enough?

I am kind of looking to get rid of the "advanced user maintenance" Windows requires.
Definitely go with a 13" Macbook Air. I have basically the same needs as you (In college, web-browse, e-mail, edit photos, documents, watching movies, DJ-ing, etc.) and I have a 13" MBP. While I love the pro, and it is definitely a great computer, I don't think I need it. I now wish I had the MBA, it's so much lighter and comes with an SSD.
Either way, you can't go wrong with a 13" MBA or MBP, but if I were you, I'd opt for the Air
