TomTom Go 930 Portable GPS Unit

If you're looking for the ultimate portable GPS navigator, you've got to consider the 930 series. TomTom's 2008 flagship models bring all of their technological advancements together with ease of use and a sleek design to present a severely cool device. For a couple of year's now, TomTom's been driving forward community-driven navigation features. They began by introducing with Map Share, which lets you instantly modify street names, street direction, and custom locations called points of interest (POIs) on your own device, then upload them to TomTom's HOME network and download changes made by all of the other users. When you do this, TomTom gets to find out what routes your device has been taking. The data is anonymous, but it's given TomTom an enormous pile of route and speed data, which they've used to tie community data to routing with their new IQ Routes™ feature, which calculates routes using the actual recorded average speeds of travel to calculate your trip rather than posted speed limits, giving you an extremely accurate prediction of how long any given route will actually take at any given time. There are a host of other interesting features, and you can read about them here.
