Given the size of Dell's Streak (it's rocking a 5-inch screen, in case you were wondering), you've probably considered using it as a dedicated routing machine with Google Maps Navigation at the helm. The only problem? Using your arm as the window mount. We heard a few weeks ago that the Streak's official car dock was finally on sale over in the UK, and it looks as if the bugger is finally shipping there, too. The best news? It seems to hold up pretty well to some of Britain's bumpiest roadways -- see for yourself after the break.
