I've always found that the middle model (i.e., the better 15 incher) is usually the best bang for the buck; and gives the longest effective lifetime before I_wanna_new_one_itis starts to rear it's head. I typically only replace my primary machine (laptop) every 3-4 years; so going low end makes me behind the power curve more quickly. Drive space can go pretty quickly . . . especially if you get either Parallels or Fusion (I have both for work purposes) and have more than one virtual machine (I do). My 160 GB drive only has about 30 GB free at this point. The video card difference is only important if you're really a big gamer; for normal use you won't see much difference. The processor speed won't be all that relevant unless you're doing big Photoshop files with lots of filters or lots of video compression or other stuff that's just number crunching. In normal use, a 10% faster processor will hardly be noticeable. On Aug 4, 2007, at 03:15, Jens Selvig wrote: > I have a G4 17'' powerbook and am thinking about upgrading to a > MacBook Pro 15".
