I work for the U.S.A. Federal Government. In 1987 (before I got here) my agency bought a Rev 4.2 A2000 and a Super-Gen so new that it came with software 0.9 and the manual had a single staple in the corner. With an 060 accelerator, a Video Toaster, & ethernet, I still use it. May well be the oldest regularly used desktop computer in the whole government.
I also have an A4000D & an A4000T with PPC & a Flyer editor. Don't do much with the Flyer these days as we bought a duel G-5 Mac based editor this year.
I regularly use Lightwave, ImageFX, (I even use AdPro for a few things.) plus DPaint 4.1 & 5, and TurboPrint to create signs, banners, logos, incidental art and the ocasional animated opening for our satelite broadcast studio.
