Long story short:
- 1983, got my first computer. Oric-1, 48K.
- 1985, West PC 800 (Apple][ clone)
- 1986, C64.
- 1988, Amiga 500.
- 1990, TI99/4A
- 1991, 40MB GVP disk for the A500
- 1994, switched to Linux/x86. Several PC's. Tons, actually.
- 2000, got an A1200 for free from a friend
- 2001, PowerMac
- 2003, A4000
- 2005, Mac Mini PPC
- 2006, Macbook Pro x86
- 2007, A600
No computers were ever sold or thrown away (except the PC's).
In summation, the Amiga is definitely the computer that had the biggest impact on me.
Oh, and if anyone out there have a time machine, let me know. I want a one-way ticket back to 1988.
