I'm not sure at what point I switched.
When I was little (birth until I was 6-7) we always had macs. My dad was the only one who knew anything about computers, and he liked macs, and thats how it was. He started with them when they were just Apples/'84 or when ever, I am not sure. Way back, though.
But then my sister needed a windows computer in highschool for some stuff she had to do. So, everyone but my dad switched to windows. We went through a few that have had issues for one reason or another (windows 98 got killed by spyware and virii before we understood that stuff, the other just didn't have very good specs, 128 MB ram, 1.7 ghz celeron processor running windows XP. Now the graphics card in my current windows machine is dieing. Still works, just doesn't work correctly.) so, I just got tired of the windows problems, part of them hardware, but just as many software (I have fixed a few software issues in windows). I've had used ibooks from my dad for maybe 3 years, and right now I have a ibook g4 that is keeping me satisfied until I can afford a new mac. I decided to get a mac next time partly because I am tired of windows issues, but also because I have gotten into video(some), web(some), music and photography a lot, and I think a mac would be good for those. Well, and I want something that just... Works.
