I have a TI but very rarely ever use it. It's not my favorite but I do play BurgerTime on it once in a while. I just didn't like how the programmer(s) did the sounds in the game. Every time you walked across a part of the burger the music would start over. That did get annoying pretty quick. Treasure Island and Parsec are fun games and I have been trying to locate a TI Invaders. I don't know much of what games are good for the system.
Putting the TI on the internet sounds like a cool idea. I've often wondered how an obsolete (for lack of a better word) computer would perform with modern internet connections...namely an Atari machine. This is one product that I might have to see in action before purchasing. Still cool to see, though.
