Ameralis Grafx has released their Tricorder PMP-09 which is one decent replica of the Star Trek tricorder, although this one boasts the ability to function as your very own portable media player. It comes with a 2.8″ TFT color display, accompanied by 8GB of internal memory, a battery that plays up to 4 hours of video non-stop or 12-hours of audio before requiring a quick trip to the nearest power outlet. The PMP-09 also supports a bunch of popular audio and video file formats, missing out on the capabilities of a browser though. You can choose from half a dozen variants to suit your preference. Prices start from $350 and goes all the way to $430, depending on the model of your choice.
