I'm one of those 'lucky' ones who had their PPC Mac Mini silently upgraded upon purchase....a week before the new Intel Mac Minis went on sale. Well, for any number of reasons, I'm finding it necessary (ok, maybe necessary's not the correct word - how 'bout 'beneficial') to upgrade. My PPC has the following specs: 1.5GHz 80Gb 5400rpm IDE hard drive 512Mb RAM 64Mb VRAM I'm purchasing a Mac Mini with the following specs: 1.83GHz Core Duo 80GB SATA drive 512Mb RAM etc. etc. I normally use my Mac Mini for some light graphics editing, a lot of surfing, some desktop publishing, etc. My question is, what kind of difference in speed should I expect? More or less stable than my PPC was? That sort of stuff.
