I've been a Mac person since 1993.
For my sixteenth birthday, my parents gave me a Macintosh Performa 200. I was stunned - we'd had computers at home since the days of the Sinclair Spectrum, but here was one of my very own!
It had a tiny black-and-white screen, came with a game to help you learn how a mouse worked if you hadn't had one before, and was, technically, portable (I also got a huge padded bag with a shoulder strap). It was way better than the 486s in the school computer room, even though those had 'Where In Time Is Carmen Sandiego?'.
I used my Performa until my final year at university, when student bedrooms got their own internet connection and I acquired a cast-off internet-capable Mac of my dad's to take advantage of this. The little guy is still kicking around, awaiting the mythical future home in which I will have room to install all my computers at once and do as yet unspecified Neat Stuff with them. I hope it still turns on by then.
When the G3 iMacs came out I was smitten. I'd never imagined a computer could be so beautiful. As soon as I could afford it I ordered a Ruby one (I wanted Tangerine, but they'd been discontinued), which was my home computer until late 2004. It, too, is in a cupboard awaiting resurrection.
I'm currently on a G5, PowerPC iMac which should probably be replaced (it would be nice to see what all the Lion fuss is about), but I'm waiting until something terminal happens to it or Apple realise that we're tired of white and we want our translucent orange computers back.
