Aside from all this, I just noticed an iMac in my local paper G3@233MHz, 128MB RAM, 6GB HD, extra 17" monitor, keyboard, mouse, SCSI scanner, software, extra network card, extra gfx card for 80 pounds. It does make you wonder why people are chasing PPC cards for hundreds of pounds, when you could get a nice Mac system for peanuts.
I think its because an imac doesn't run amigaos:-D OsX won't run very well on a 233mhz/128MB machine and classic macos is crap imho.
