We've already heard plenty about the custom PDAs that census takers will eventually be getting their hands on, but Popular Mechanics has now taken things one step further and actually gotten a hands on with the device itself (or at least the current form of it). As we knew before, the PDA is made by HTC and based on Windows Mobile, with Florida-based Harris Corp. handling the actual deployment of the devices, which are expected to eventually total some 500,000. While complete specs are obviously still up in the air (given that they won't be deployed until 2010), the devices will apparently boast 10 hours of battery life, and pack integrated GPS to keep all those census takers on the right track, not to mention a built-in dial-up modem to ensure they stay in touch when venturing beyond the boundaries of Sprint's data network. If that's not enough to whet your appetite, you can hit up the read link below for a video walk through of the device.
