I had an Oric Atmos (my first computer), a C64, a MSX (for a while) and after that I switched to consoles and ended with an arcade cabinet in 1992 (I was totally addicted to retro arcade games) and some months later I bought my first Amiga.
I used the A1200 as primary computer until a friend built me a pc in 1998 when I was student because I needed one to work my class projects (Photoshop, Director etc.). It was a P200 I overclocked to 225 Mhz ! ;-)
My second pc was a XP1800+ in 2002, I've flashed the BIOS and I could upgrade the CPU to a XP2600+. I use it mainly to go to the web, and to calculate proteins for the FightAIDS@home project, but it's not very fast to compute the blocks, that's why I'm looking for a second hand Cray T3e. :-D
But my fav computer is the A1200. I use it quite often, mainly for drawing, playing some games, and to test some soft I grab from Aminet.
