I want to try out a Mac, looking online i can get a G5 Imac with good specs for 400-500$, although this is a good price for me, i am worried about what if i dont like my mac? what if i want to run some windows software, how bad off would a Windows power user (serious power user,hacks, mods, programming, ect...) be if he switched to a G5 computer? any opinions about spending the extra 150-200$ to get an intel mac instead?
