I used to work with OS 9.2 and didn't really think much of Apple back then.
I went crazy when I saw the GUI of Mac OSX 10.2, geez, windowze looked so primal when looking at the mac interface. I mean, I thought that Mac's were so expensive that I could only dream about having one (this was in 2003). After that I started working more with OSX (10.3) at school and went crazy with Exposé. Finally, when 10.4 came out I drooled with dashboard and spotlight and just knew I had to get one. Right now I'm one day from getting my iMac 24".. I can't stand the wait 😱
