24 years old from .dk, been using computers for "a while".
Started with a Commodore 64, later upgraded to amiga 600. For a while my PC access was limited to school computers and when I visited my dad.
Then came 486dx4-100 -> pentium/mmx-200 (new box) -> amd k6-II 333mhz (same parts as the pmmx, borrowed mobo+cpu from a friend) -> athlon700 (new box) -> P4 2.53GHz (new box) -> AMD64 3500+ (new box) -> AMD64x2 4400+ (new cpu+mobo)
That's the chart for my "workstation". I also have a p3-celeron 1.3 working as server, and I have a p4-celeron 1.7 that used to be my secondary workstation, which my younger brothers have inherited (along with the main P4). For win9x/win2k/linux/osdev testing I have a p2/mmx 350MHz which a friend of mine found lying around at his company's basement
I really wouldn't mind playing around with some embedded-size computer that still has reasonable power - like somehing ARM based, or perhaps just one of those nano-ITX boards from via. But it's a bit much cash to spend on something that I'd only toy around with
