So, anyway... that's a decent deal on a Mini?
Yes. the 1.5 is a silent upgrade with an additional double the VRAM. They were not produced for very long before Apple switched to Intel.
If I remember right the 1.4 I have has 32MB and the 1.5 is 64MB. (or is it 64 and 128?)
I would get one for that price but its not a substantial upgrade to my 1.4 and I got a Powerbook5,8 with 2GB ram and 128MB VRAM just waiting for Morphos 3.0...
