I have a 1st gen. G4 450 "Sawtooth", which even with 768 Mb RAM runs now at a snail's pace. It is up to date with iLife and Panther, but at 5+ yrs. old it is time to replace. Do I get a 1.42 gHz Mac Mini with a Superdrive, which is more cost efficient, use my current 19" LaCie Electron Blue monitor, which is large (depth) but fantastic (and I have a corner desk so space is not an issue), arm it with bluetooth and airport for the wireless experience and put my 120 GB Western Digital SE HD in a firewire case for music and video storage, or Spend about twice that for the new 20" iMac 2.0 gHz (when it is released), in which case only boosting the processor performance in the System Prefs to the max will actually give me an increased performance over the Mini (at least according to all the bench tests I've read). And will there really be a bigger difference between them once they are running Tiger. How well will Tiger run on a G5 or how poorly on a G4, comparatively.... Major uses are iMovie, iPhoto, some Garageband, and a whole lot of email and surfing. Don't really do much Photoshop or other graphic design anymore but may also be running FCE soon. Input greatly appreciated. Thanks.
