Just FYI, I did a little experiment to try to model the GSM interference using my Motorola phone, a small antenna, and a scope. I then built a model in octave which generates a wav file that sounds similar to the interference from the GSM data packaets. The code and wav file can be found here: http://www.pldr.org/?page_id=161
Software writes "Reuters reports that Microsoft is developing an iPod and iTunes Music Store competitor. Few details are available, but it's known that Robbie Bach (the man behind the Xbox) is heading up the project." From the article: "Most iTunes rivals charge monthly fees to access a catalog of entertainment, but some allow consumers to buy individual songs for about $1 each. Microsoft's service will emphasize the pay-per-download, or a la carte, model, the sources said. A subscription component will also be offered, according to early accounts of the planned service. One source, who has seen a demonstration of the service, said it was an improvement over iTunes."
