There's been so much chatter about Apple iCloud that you'd think the streaming music service had already been announced and the deals inked. But it's still just a rumor until an Apple executive takes the stage and unleashes the Amazon Cloud Player and Google Music competitor in a spate of superlatives. That hasn't stopped  Businessweek  from stepping up with a good summary of all that is "known" thus far, while giving us some insight into the particulars of how the service will work and the motivations to make it happen. One revelation, sourced from three people in the know, claims that Apple will scan customers' iTunes libraries (hello, LaLa) and quickly mirror the contents on Apple's own servers -- no massive DSL-choking upload required. And Apple will do you the solid of "replacing" any low bitrate tracks with the "high-quality" versions it stores in its fully licensed music locker for streaming to your connected devic...

Well, this might be a good reason for The Powers That Be to know your exact whereabouts. According to a team of MIT researchers, speeding up data rates on mobile devices could be as easy as tapping the various motion sensors found in run-of-the-mill smartphones. The scientists believe our wireless infrastructure is at the root of bottlenecks, with a handful of weak transmitters clumsily "handing off" data to one another as you move out of range. The solution: use GPS radios, accelerometers, and even gyroscopes to infer where you're headed, and then choose an access point near where you're likely to end up. The difference, they report, is dramatic: a 50 percent boost in throughput, along with improved success in choosing the best bit rate. To boot, if a base station is armed with location-based info, it can better predict when the devices connected to it are on the verge of losing contact. That's all good news, but sadly we doubt any amount of promising science is...
