I recently came across a new company that has a rather interesting new product. Bug Labs makes a small, cheap, open source computer that, combined with addons that you can purchase, make this endlessly hackable. So far they only have four modules (a screen, motion detector/accelerometer, GPS receiver, and a digital camera), but the company promises more in the future. These additional modules are designed to just snap onto the base and immediately start working. Bug Labs even provides a place on their website where people can share programs they made. With a software development kit available, the possibilities are limited only by your imagination and patience.
