Normally, I would not plaster an ad like this right here. However, if you look at the list of the top 500 supercomputers in the world, a bunch of them are built with IBM G5/POWER chips. Personally, I am glad Apple has expanded to include x86, but this mostly has to do with Motorola's offerings, not IBM. These iMac G5's are gorgeous machines. My sister has one, and she absolutely loves it. The #1 rule of life is, don't argue with your sister.
