We love the modular equipment from Bug Labs, but this patent from Microsoft takes the enthusiasm of interchangeable tech and cranks up the practicality. In a long, somewhat convoluted patent application, Microsoft pitches a modular GPS system. But through their explanation, the device becomes increasingly complicated, including "two-way cellular communications" across a "voice network" and a "wireless modem and digital camera." Through the modular arrangement, the "base unit realizes reduced bulk and complexity." Ultimately, we're left with a really geeky piece of tech for which we'll always be losing a piece between the seats. [Patent via Unwired View]
