I have both the Apad Irobot and the Eken M003. The Apad is by far a better device. I can hook it up and sync it to the computer using T-Mobile's cellular phone software. It also plays youtube, and a lot of different video files. It also has android market installed. Eken M003 is just a cheaper device that is able to do facebook, email, ebook reader and simpler software. Depending on your use, you may only need Eken. If you have the money, buy Apad Irobot but make sure it is newer model with camera.
