I was just wondering: what does the oldest usable PC in your arsenal have on it and what do you use it for?

At home I have a laptop I purchased in early 2000 that was top-of-the-line at the time.  Pentium III, maxed out memory and a PCMCIA wireless card.  Pretty nice, really..kind of bulky, but I liked having a big (15-inch) screen and both a CD drive and a 3.5 floppy drive built-in (OK, so the floppy dates it....).  As soon as Microsoft started allotting laptops for employees it fell into a bit of disuse.  However, when I go to conferences or retreats of a personal nature, I take along my old laptop.  It has Windows XP SP2, the latest versions of Microsoft Works and Microsoft Streets and Trips along with the usual sprinkling of utilities and games.  It's servicable...and I still really like the screen real estate.

So, wondering out loud, what is the oldest usable PC or laptop that you still actually use?

Just curious...
