It's all in the right keyboard with those Atari's. With 80 Columns, the Atari makes for a great work processor and an excellent means to run Lotus software amongst other things.
I only wish it had an audio program that supported MIDI and allowed for acess to at least 8 channels. Duel Pokey of course. 
Improved sound would be nice.
Graphics aren't bad for an 8 bit machine though.
Right now I have a friend developing a V9958 based board for the Color Computer.
If I can combine Sprite Graphics with the Coco3's 640 by 220 pixel graphics and my own sound board I may switch back to that platform.
2 MB of memory goes a long way with a 6309E processor.
