Jason writes: "EHX has returned this year with renewed vigor. The electronic house expo has been around for quite a while. This year as was last year the expo is sponsored by many different organizations among which are Tech Home a division of CEA and CEA itself. The electronic house expo is the traditional venue where companies are able to demonstrate new technologies that range from security and wiring to audio and computing. With the advent of Microsoft Vista and Media Center we are now seeing unifying technologies arise that give home owners the ability to control everything from their audio, TV, and home lighting to their security systems and computer.
