We caught an unofficial glimpse yesterday, but this morning it's official: Apple has a new Bluetooth-enabled Mighty Mouse mouse. New features include laser tracking and the aforementioned Bluetooth wireless connection, and it runs on two AA batteries. We're sad to see that Apple's press material makes no mention of other improvements to the design. Apple is known for making unannounced tweaks to its products, so we'll have to get the final product in hand before we can pass final judgement. We'll get right on that.
