i own a 1.83ghz, 60gb hd, 2gb ram macbook. recently i have been thinking about upgrading the HD. 60gb SUUUCKs and i'm sick of it. option1: i could buy a new HD for $100-$150... solves my biggest problem with the machine, saves me some bucks from buying a new computer, if i bought a 7200rpm HD i'll see a bit performance improvement in some areas. option2: on today's market i could probably get $700-$750 for my machine as is.. if i put in the hard drive this adds up to me owning a $8-900 machine (as i see it) ... with this in mind i could spend just $300 or so more to get a brand new 2.4ghz, 160gb hd, 2gb ram macbook. warranty, new computer smell, new battery, quite a bit more nimble processor (although 1.83 is no slouch).. i think you now see where i am going with this... in your opinion which would be my best route? this is all personal choice stuffs. just for ***** n giggles.
