The Atari Flashback Portable actually did surprise us!
Unlike some other of the AtGames handhelds, this one is really good.
The LCD is crystal clear and suited for fast movements - it works perfect with Atari games.
The controls are great AND besides the 60 built-in games, you can even load hundreds more off an SD Card!
And finally, if you want to play on the big screen, you can use a 3,5mm -> Composite A/V cable to connect it.
The only thing lacking here would be 2-player support... but if you're not interested in that, it's certainly worth getting it!
To find out how to put games on the SD Card (and grab a pre-made package of games) as well as get more information about it, check out this forum thread on the AtariAge boards!
And here is a list of the included games:
Demons to Diamonds™
Frogger (new port specific to the Atari Flashback Portable hardware)
Frogs and Flies™
Fun with Numbers
Pong (Video Olympics)
Return to Haunted House
