Back when most e-mail was still text only, I preferred using my CoCo over a PC. When it started becoming difficult to
view even Delphi pages without full graphics, I finally relegated my CoCo to some programming, experimenting (especially 
with hardware), and a couple specialized tasks (like keeping the mailing list and printing labels for "the world of 68' 
micros". The CoCo has its limitations as well as strong points. It's no longer well suited as a general purpose computer.
Technology has passed it. It is still optimal because of its robust simplicity for many hardware experiments. The CoCo 
has outlived the usefulness of the other "home" computers. Trying to make it do much more than the hardware can pratically
cope with only serves as a programming learning experience at this point. Some things just need to be accepted. 

While making an upgraded system using things like programmable logic chips does seem appealing, it is mainly a learning 
experience also. PC emulators appear to be the "best" CoCo upgrade on the programing and software compatibility level,
especially when the emulator is writtten in such a way as to take advantage of the PC hardware as well as be backward 
compatible. If the hardware emulator (programmable logic) based machine is as rrobust and easy to program and interrface 
to, it would be the "best" for hardware experimenters. Maaybe a combiination would be goood though -- an emulator with a 
hardware card that brought the most used programmable lines out the back of the machine. I suppose that would be difficult
to do though. 

Please forgive any spelling erors, my keyboard is acting up right now! I went back and fixed at least most of them though.
