In Car PC
My current in-car-computer consist of a Dell Inspiron Notebook that has been cut down. If you have ever owned one of these laptops then you are probably aware of the keyboard issue (the keyboard has a tendency to die). A search for these keyboards is fruitless (over $40 for a laptop keyboard is not my idea of a good deal). I could hack in a cheap usb keyboard but that just wouldn't look right (and I have other laptops for my general use).
So what did I do? I ripped the keyboard off of it. folded
the display back on itself, now I have a very nice "removable"
in-car-computer.
I am using a delorme earthmate usb GPS receiver, which has been painted black
(the bright banana color was the equivalent of a "steal me"
sign)

For Mp3's I use Winamp
OS is Windows 2000
The good thing about this install. I can unplug and pull it all out
(to take in the house for testing etc).
Its also easy to put back into the truck at any time.

This is a picture of the simple mount I made, The top simply screws on and
off.
I can also unscrew the mount at the base.

Here is a picture of the computer, mount, and the inverter
which is used to power the system
