A course at the University of Michigan ends with a live concert featuring students using iPhones as instruments. “Building a Mobile Phone Ensemble“ teaches students to code musical instruments for the iPhone, using the Apple-provided software-development kit. Georg Essl, assistant professor of computer science and music, says, "What’s interesting is we blend the whole process. We start from nothing. We teach the programming of iPhones for multimedia stuff, and then we teach students to build their own instruments.”

Kawahee was one of several readers to tip news of a price cut for the Xbox 360. This comes after Sony dropped PS3 prices and unveiled the Slim model last week. The 360 Elite will now retail for $299, but will no longer ship with HD cables. The 360 Pro has been reduced to $249, but Microsoft is phasing it out. Analysts don't expect this new price point to be a huge boon for sales because the Elite doesn't match the PS3's hardware capabilities and is still more expensive than the Wii. Microsoft has "no plans" for a smaller version of the 360.
