Name: Buffalo DH-KONE4G/U2DS
Category: 1-seg tuner
Price: JPY15,700
Release date in Japan: Late April, 2008

It's twice the price of the Corega CG-1SGT appearing at the same time, but Buffalo's USB tuner adds 4GB of built-in memory, and works with Mac OS X as well as Windows. You can record up to 20 hours of programming onto those 4GB, says Buffalo; the "PCast TV fro 1-Seg" playback software is inside, so just carry the dongle with you to play back the recorded shows on whatever PC is handy. Better yet, move the recorded files to a microSD or MemoryStick card via the PC, and watch the recorded content on your mobile phone, PlayStation 3, or PSP. Naturally, the device will also function as generic USB memory for storing whatever you like.

A long list of additional features includes long and short antennas, USB extension cable with dock, EPG/iEPG, digital radio (play and record), digital playback enhancements for smooth motion and clear text, scene search, color correction, "timeshift playback", forward-skip, and screen shots. Finally, with two of the units plugged into your PC, you can watch/record two programs at once, switching freely between main and sub screens.
