Sony Mylo has a Flash Lite 3 player. In fact it is optimized for On2. There is apparently quite a bit of games collection available for it from Mylo portal. To access it, one has to go to http://www.sony.com/mylo from the Mylo device and they can access it.

The announcement is available on Mylo forums here.  The page lists Sudoku, Solitaire and Pait-it as games available.
