You actually know what some of the crazy doodles on the side of an HDTV means when it comes to video--720p, 1080i, 1080p. Congrats, you're ahead of most people, like my mother. But do you understand the alphabet soup of audio, the confounding constellation of logos on your Blu-ray player's box?

The Gadget: Aerielle's i2i Stream allows users to share audio from any source between two or more i2i devices using a wireless 2.4 GHz frequency. Just plug in a set of headphones and listen to the music your friends are broadcasting on their i2i Streams (up to 7 audio sources).
This image of the Samsung U4 MP3 player appeared on Samsung's Korea site over the weekend, promising "freedom from monotony." And while there are no hard specs surrounding this rendering except that it's "coming soong," it will likely pick up where the Samsung U3 left off, which is to say it wants the iPod Shuffle's head. [
Some information has leaked out about Samsung's upcoming M3510 music-player mobile phone, and it looks like it'll have some accelerometer-driven control built-in. A bit like the
