I currently use my Android phone to play music and make phone calls through a Bluetooth-FM adapter in my car. I just got a Bluetooth-OBDII adapter (eBay, $20) and the Android Torque app (https://market.android.com/details?id=org.prowl.torquefree) which can show just about any operational parameter of the car - speed, fuel pressure, coolant temp, trouble codes, etc. There are only a few things I can't do through the Android - control the temperature and turn on the headlights. That and having a good place to mount the Android is the only thing missing now.
Although technically only the first one is necessary since most people get the second two plus many more from having a smart phone with a data plan.
</snark> On a more serious note, how many times have we heard such things, and why has it taken so long? People have been using crappy GPSes for quite a while now, and more recently their cell phones to do things the car manufacturers have known about for years, but done nothing to support.
P.S. Considering that the big cost of either system is the 3G phone plan and that people tend to replace the hardware of the computer they take everywhere significantly more frequently than they replace their cars, I think it's pretty obvious which option makes more practical sense.
