That was a very interesting test. If this came out this would have been great.
The screen seems poor, though, especially with the reflect.
Funny how they did touchscreen before colour.
So did Casio (with the Classpad). I'm guessing the PLT was meant to be a direct competitor to that.
Actually not really. Casio had color calcs since 1995 and their first touchscreen calc came out in 2003. TI worked on that cancelled device around 2003-05 or so I think but they didn't have color screens until 2011.
