Personal Tech Pipeline got a chance to tour around with Mio's C310
portable GPS receiver with built-in DAP that we first spotted at CES, and claim that although the unit is a pretty good value, its performance is a bit underwhelming. Rather than building a product from the ground up like the Garmins and Magellans of the world, Mio has assembled a Windows CE-powered unit featuring software from Destinator Technologies and maps from TeleAtlas -- which, while not necessarily a bad thing, means some of the features aren't as polished as they are on vertically-integrated products. For example, PTP found that many important options were buried under several sub-menus, which made simple tasks like changing to night mode or selecting a new destination while driving more difficult than they should be, and probably more dangerous. The C310 seemed to perform its navigation duties fairly well, though, and even ships with ActiveSync for loading up your Outlook contacts' addresses, but little annoyances like a cluttered 3.5-inch screen and awful built-in speakers might be enough to convince most folks to put their $600 towards a more expensive model that operates a little more smoothly.
