I happen to have a blue iMac G3 from 1999. I have it in storage somewhere, got it secondhand. I used to have two Macintosh Plus' from the early 80's (my parents bought both of them new), but they ended up selling them (one of them had a screen that worked half the time, other one worked perfectly).
I also have a Mac Mini from 2005, got that brand new. It was my first new computer.
