hello. i've lurked for quite a while, but this is my first post. i hope you'll bare with me as i gather my thoughts. i might ramble. i'm a college kid who's about ready to fling his aging dell laptop out a window. rage aside, i was given a ray of hope this week from my uncle. he has a nicely used 17" powerbook G4. 1Ghz, 512mb ram, 60gig hdd, super drive, airport extreme. it has a good chunk of warranty remaining and from what i've been told is in near mint condition. a major plus for me is that he's willing to let me have it for $1000 AND is being kind enough to let me pay him whatever i can on a monthly basis until it's paid off. i've been saving what i can for a new laptop, but it's a tricky situation with the start of a new semester and other expenses. my exposure to apple/macs (excluding my beloved ipod) has been somewhat limited: a few friends have ibooks, the art department harbors some G5 powermacs, and one of our libraries houses quite a few emacs. however, my experiences have been positive. so i'm keen on the idea of taking up this offer from my uncle. outside of the usual stuff, i do a lot of photography work. converting raw files, scanning slides, etc. i already know i'll have to add more ram. so after all of my rambling, i'm just curious to see what you seasoned users have to say. good investment? bad? any advice/tips? thanks! **oops, had to edit it a bit. i meant 17" instead of 15" and super drive instead of combo drive. sorry for the mix up.
