Even cheap flat panel TVs usually have a lonely Composite jack somewhere on the back, just in case someone's grandfather wants to plug in the VCR. Of course this means you'll be limited to NTSC resolution and probably a fuzzy picture, but it's $9 and has built-in Wifi and Bluetooth so you don't need to hang a wired keyboard off of it like you do with the Pi. I'm not sure what I'd do with this, but that's true of all of these cheap little SBCs, and I usually find something worth doing.
The handheld version with the GPIO pins sticking out seems pretty cool. I'd really like to feel that keyboard before committing to it though.
