Jane, get over the bitterness and rants and get over to eBay. It's easy to complain and whine, and just as easy to bid, and both are probably equally fun. If you lose a bid, you can enjoy the best of both worlds.
I have everything from TRS-80s to Jaguars. The CoCo 3 is still my favorite, probably because the CoCo 1 was my first computer. I still think the 6809 has the most elegant instruction set of any CISC (if it could be called that) processor. Certainly better than the miserable x86 we suffer from.
The best machines for their time were probably the Atari 800, which was WAY better than competing 6502 products like the Apple II, the CoCo (with the very powerful 6809), the PC jr.(great sound and graphics), Commodore 64 (the sprites really helped) and Atari Jaguar(crazy speed for the time. The Atari 7800 was a nice machine too, it's really one of my favorites because of the compatibility with the Atari 2600. The Apple II GS is a nice machine too, it has great sound capability and the queer graphics modes of the Apple IIe (you had resolutions and colors, but with important, and strange, limitations as to what pixels could be based on what was around it) were no longer necessary. But, there is not so much software written specifically for it, and most of the time you're stuck with 8-bit 6502 software.
I leave out microcomputers who's main focus was not gaming or home use, of course, as PCs, Amigas, etc... could play games, but they were not designed primarily for the home or gaming.
If I had to pick one, I'd say within the context of when it was created, the Atari Jaguar had to be the best. There was nothing close to its capabilities at the time, unlike now when the you have three bad consoles. One unreliable, one a joke, and the other too expensive, and too hard to program. You know someone at Sony is seriously demented when they tell the world that being difficult to program is a good thing and will help the longevity of the machine. He must have been talking to someone that helped develop the 8086. After all, no one liked the instruction set in 1978, and it's still around.
