well i decided to write this for people who dont want to use mac os x or just want to run windows on a macintosh or even linux well lets begin windows: if you want to run windows on mac there are several options 1. bootcamp: allthough still in the beta stages this option will be most common on intel based macs good: this application gives you the option to choose which os to boot bad: this application leaves hundreds of thousands of mac owners that do not have a intel procesoor out in the cold. 2. virutal pc 7: this option is common for all mac users that do not have a intel based processor good:nice application but has problems with emulating windows fast enough bad: to expensive processor entensive only supports windows xp doesnt support 98 2000 me 2. cheapest if you can find it on ebay is connectix virtual pc 6 is basiclly virtual pc 7 with better support for older and newer operating systems now lets talk about linux there is only one version of linux i would recommend for mac because it works and functions with mac os x drawback is you loose mac os 9.2.2 but it is still the most easyiest solution for linux on mac it is freeware but you have to download it from the manufactures webpage via legal bittorrent this application is fully open source and last but not least 2 other not so popular options 1.imac and tower firmware hack this option basiclly updates the firmware on the mac to convert the mac into a ibm computer drawback once this is done you are never going to run mac os x again 2.unix-drawbacks no os x support on mac version
