It really comes down to personal preference. I use Windows and don't mind it most of the time. That said, my main machine is a Mac and I love it.
i will mainly be using the laptop for school and sometimes for gaming. games like counterstrike, source, starcraft, and i might wanna try quake 4. but games are no big deal, if i can't play em on the laptop then its not a big prob.
here are the specs of both the dv2700t and the macbook though, let me know what you guys think is better.

Where are you buying this older MBP from? It could be all you need for the time being or even a couple of years. But it is definitely getting on in years and a new regular MacBook will outperform it most of the time, plus a new MacBook will come with Leopard. I'm with the guys who are saying to wait for the refresh; it should happen in time for the last minute back-to-school shopping frenzy. With the Penryn/Montevina, the MacBook will likely be a better deal anyway (price/performance-wise), especially since prices are likely to drop $100 across the board.
