Take this Gemei HD-660. Sadly it’s only available in China at the moment, but it features a 4.3-inch LCD with a 480×272 resolution and can handle most popular video and audio formats (AVI, FLV, MPEG, MP3, WMA, FLAC and more).
Now, obviously, playing back 720p video (or even standard DVD video) on something with this resolution is fairly pointless as you won’t see the difference but it comes with an external video cable so you can hook it up to a TV.
It even has a remote control so you could take it with you, plug it in to a home entertainment system and control it from the comfort of your chair. 32GB of memory means you should be able to fit a decent amount of high definition video onto it, or tons of music.
