My first computer was an Tandy 1000EX (in... 1986?), and this article is spot-on. The sound and graphics were miles ahead of my friends with IBM and Apple PCs at home (but not quite as good as the Commodores). And, as the article points out, they didn't keep up with standards. I made the mistake of going with nostalgia and "upgrading" to a Tandy 1000TX in 1992 when I headed off to college, and everyone else was running Windows (my old Tandy could run Windows 3.0, but not 3.1). I ended up needing to do my homework on my roommate's Wang (another dinosaur) PC.
Still nostalgic for my first Tandy 1000, but I regretted my decision to get the second one, and ultimately sold it a year later to buy a no-name 486 PC.
