well i know you can install mac os on a pc if you use hackint0sh its not official but can be done, i have not been able to install it on my test laptop due to not knowing what drivers to install..
but its so very different i have used macs in the stores public and in england while i was there, it was like i had never touched a pc with mac its easy to use but you just have to figure out where everything is and the more i research the programs the more i like the ones on the mac more then pc, so after many times of trying to install mac os x on my laptop i figure also its 7 hour battery life i could use it in college.. imo it seems to be very good. and if i hate it i can sell it on ebay or in cyprus. here we have the old macbook pros for 2,500 they try ripp us off :/
