1. i am a MorphOS user. i have MorphOS running on a G5@2.3GHz. Soon also on a PB 5,7
2. you compare a towerized system which consumes more energy and therefore costs more to an i5 laptop. lets stay at mobile machines or compare a G5 to an adequate x64 towerized machine in the same price range.
3. Depending on your hardware OS4 runs a lot faster than a CSPPC. Look at the link i've posted earlier.
4. As stated before probably 99% of the people do already own a modern x64 machine. So they don't have to buy extra hardware, which ultimately means you would only have to pay 29,95 Euros for OS4.1. If you wanna use or test MorphOS you HAVE TO buy old/outdated or new and overpriced hardware.
