I just installed the latest version of PearPC (0.3.1) on a P4 2,6GHz HT. It's surprisingly fast and responsive. It kind of reminds me of trying 10.1.5 on a 233 MHz Powerbook Wallstreet with 96MB ram. Okay, too slow to do serious work, but it shows to have real potential to become a serious 'alternative' for PC users who want to use Mac OS X. Processors will only become faster and PearPC will surely improve a lot in the near future. I'm convinced, PearPC is a force to be reckoned with!
