If you've wanted to play chess on your reader, it's now possible with the PRS-T1.
The touchscreen and browser's good javascript compatibility makes it pretty enjoyable: castling and pawn promotion are present, along with an 'undo' button.
Just go to

There's many other javascript games available, have others found some that work well with the PRS-T1?
