I used to have a pink netbook that ran Microsoft Streets and Trips that I used together with a Bluetooth GPS. I had a power adapter that plugged into the cigarette lighter of the car and also a line in cable for the stereo. I could play music with Windows Media Player and have turn-by-turn directions work flawlessly. It was particularly good for road trips with a navigator in the passenger's seat as it had a great user interface for managing large numbers of points of interest and making routes that hit multiple points. It was the best satnav I ever had.

I remember the time I was heading south from Syracuse in an area notorious for state police speedtraps when I had pulled alongsides a greyhound and my son had logged into the WiFi on board the bus. The bus driver got pissed at us and got up to 95 mph to shake us. I gave up first but I figured he'd have a lot more to lose from getting a ticket than I would.
