I'd like to get a 20" cinema display for use with my Powerbook 15" (and eventually the G5 I'll be getting). I edit some video (FCP) but not professionally, plus other general stuff though not much regular 2-D graphics. Is there significant big advantage of getting the new aluminum vs. the old beyond aesthetic preference -- I think I may actually prefer the look of the "old" ones? the price is roughly equivalent and I don't much care about the $100 difference. Will the new one be easier to use as a TV screen someday should I want to do this?
