Switched.. at birth
My first Mac was a Plus, I think 1987? My mom bought it for me after using a Apple II in school (plus my handwriting sux). In the `90's, gaming was all the rage, and you had to have a PC, so I built one, and ran them side-by-side. I still have both PC's and Mac's, they each have their niche in my home. One PC for TiVo, until a real, quality PVR solution for my Mini. Two PC's for Domain Auth. and storage (1TB), until I can justify the cost of Xserve and Xsan. But I don't go anywhere without my Powerbook, and my Mini runs 24/7 in my room, waiting silently (wish I could say that for ANY of my PC's) for any command. I love OSX, everything is truly easier, and now I'm learning to use the Terminal to run open source apps. This makes the posibilities endless if your willing to dig into the core of the OS.
I have spent most of my life fixing computers, profesionally for the last 5 years. PC's freak out on people for the most random things, they loose data, BSOD, or just get Hijacked by spyware and viruses. Not to say Macs don't have problems- my mom's G4/400 PB was a little buggy, but well past the warrenty, and I have crashed OSX twice. Both times I had seriously damaged the file system messing around in terminal (installing GNOME, and some other random apps.). Right now I'm saving my pennies for a iMac "20, I need more power. I will (hopefully) never need to buy another PC, I will rather find a alternative for the Mac.
