So I'm jumping from PC to Mac tomorrow, looking at the MacBook... MBP is too much computer for me. I burn DVD's, download torrents, surf the web, and use iTunes mostly. Pretty basic stuff. Don't need the backlit keyboard or extra 70 gig HD, however the 2.0 processor worries me a bit. Will this be enough when Snow Leopard comes out? Would the extra .4 even be noticeable in the new OS? Also, I plan to add 4 gigs of RAM right away. Any advice is helpful since I've never used a Mac before and don't understand how 'heavy' the OS and programs are, or will be in the future. Thanks guys!
