One of the problems with the pricing structure of American carriers is that people who buy their phones outright don't get any kind of break on the service plans themselves, giving people fewer incentives to get away from subsidies. T-Mobile has addressed this (by essentially throwing out subsidies all together), but today AT&T fires back with the new Mobile Share Value Plan. Basically it's a $15 discount if you buy a phone unsubsidized, including the new AT&T Next plans, or if you've already paid off your on-contract device.
A few days ago, I posted about a student project at a Russian University that aims to run two or more instances of Android at the same time on a single device. It's a technology called virtualization, and we already use it on web servers and developer machines everywhere.
At first glance, the idea sounds interesting, but seems to lack practical uses for the majority of people. Sure, some developers will save a few hours on testing, and industrious users might want to run the latest CyanogenMod nightly ROM alongside their daily driver, but this kind of stuff doesn't really appeal to your neighbors or parents.
