I own a mac and tried to switch to a pc, so i spent 1110 dollars on one. I thought that I would use it to play games and use it to use all those applications that I thought i wanted to use. A couple months passed and none of that actually happened. I found myself too busy(school, family, friends, etc) to sit down and play games and i didn't really need to run any special apps i found out, because most of the time i could find something on the mac to do it via osx or x11. So my pc sat off for a while, barely getting used. I finally turned it into a tivo like device and it finally gets some use. I could have just bought a tivo w/ lifetime subscription and still saved money. Other than that, i haven't needed windows. I honestly detest windows, everything from the folder structure to the gui.
I agree that owning a mac aint cheep and the hardware isn't always the fastest but generally, i like my mac and mac os x better than any pc with windows. And i really disagree that there is nothing ever that creates interest. I just bought ilife 04, (itunes, iphoto, idvd, imovie, and garageband) for 50 bucks and garageband is amazing. I am actually making music, and its really fun and easy, if anyone wants screenshots let me know, or samples of what i have done in a couple minutes today.
