I am buying a new mac soon. (joy!). I have a g4, 867, powerbook and was considering an iMac for ease of use/space/etc. I am a busy photographer and the 20inch appeals to me. But, when will the g5 actually be reaching the imac model? I don't mind the imac being non-upgradable-- my pb has served me fine but I want to buy into an acceptable speed and ride that model out for awhile. If it's going to be months I might consider buying now-- but would really feel like an ass if the g5 hits the imac in march or april.
