I used to own the powermac dp 1.8 system. I have since purchased a refurb 24" Imac. I have to say this thing is AWESOME LOOKING! I do a little bit of audio and video editing. I somtimes miss the powermac but it might just be me. I do see a little speed improvement via the intel machine. I need to upgrade the ram to 2 gig also. Anyone having second thoughts or is it just me?
