macbook pro is a much better laptop than anything else you're going to find on the market. some people might not like the OSX software or the limitation of having a 13in screen, but for the money you're saving in the long run, it's worth every cent. granted, you can get a 15in screen but the GHz is only 2.5 compared to the 2.9GHz available on the 13in. my first macbook i bought back in 2009 and it went through tons of shit with me being at college and taking it on tour. it got dropped and a whole water bottle spilled on it, it was ruined. i just bought a macbook pro this year, love it, love everything about it.
if you're going to be doing any recording of music on a laptop i highly suggest going with the mbp. there's not another laptop that has the consistent capability of recording audio with the lowest latency possible, and mbp has the thunderbolt port, which is the port of the future.
