Over at the Register there's a pretty in-depth review of the Medion MDPPC250 GPS Pocket PC. It's the latest in the crop of cheap PDA/GPS combos that have been coming out recently. The PDA part has 64MB memory, along with SD and CF expansion slots and runs on Windows Mobile 2003. As for the built-in GPS, mostly it's a low-end option which, while not skimping on basic quality, does leave out some features and some of the more refined navigation software (you'll probably have to spring for something decent yourself). Still, if you're in the UK on a budget and need some help getting around the maze-like streets of London, the Medion'll get the job done — and it doesn't look half bad either.
