It all starts with the music IMO.
I remember being a kid and listening to 'Master of Puppets' on a crappy walkman in the back of the car, and loving it, as my Mum & Dad took us on the long drive to visit relatives in Scotland.
I guess it snowballed from there.
If I didn't have the love for listening to music, I wouldn't have bothered buying 'decent' kit. Much the same as I'm not a massive gamer, so still have a PS2 (along with a Wii). If I was a gaming freak, I'd have a PS3 or ultra high spec PC. I don't think if I had a PS3 I'd be any more of a hardcore gamer than I am.
