seeking opinions, advice, etc... decided i am going to get something. a new toy, to play with. and the choice between the 20" iMac g5 and the dual 1.8ghz is very close indeed. the powermac hasn't really got a lot going for it. it has dual processor and a faster bus. oh and the faster superdrive. these are the only things that would affect me. the main factor should be the screen. i have only 17" crts. how big is a 20" widescreen lcd by comparison? huge? minimal? i would probably upgrade to a new imac with subsequent revisions. am i correct in assuming the 20" imac would have a higher resaleability value? thanks for any ideas that help me decide.
