Hey guys...am thinking of getting a new SR MB and wanted to know if there is any noticable difference between the 2.0ghz and the 2.2ghz macbooks? The combo drive thing doesnt really bug me (that much), as i am a student on a tight budget and wanted to get an external monitor to keep on my desk and could get that with the money i save from getting the entry level MB. Also, is it hard to upgrade the hard drive in the Macbook? (as easy as upgrading the RAM?) And what sortve HD should i be looking to get? I know thats a lot of questions, but have a bit of a dillema!
