Laptop Minimum Requirements

I should have mentioned, second hand is fine

Mike,
Believe it or not, I was running an old 486-DX4 laptop, which struggled, but ultimately ran OziExplorer ok. Photos were a breeze.
Picked up a cheap Pentium 233MX on Ebay, which runs OziExplorer like a breeze on Win98. With a cd-rom, I can download the maps I require, while leaving lots of space on the hard drive for photos. I have a 3GB HD and it's heaps.
The best part is that if it gets knocked off, there's only a couple of hundred bucks lost. A CD writer would be a good idea to off load pics before they get knocked off with the laptop. You can get a USB external CD writer for not all that much money.
Alternatively, there are some bargains going now on new laptops running Celerons for under $1400 which will play your DVDs. One problem with modern laptops is the lack of RS232 port to interface the GPS; some USB-RS232 converters don't seem to work with the GPS. Check OziExplorer; I think they're writing a USB interface for some model GPSs.
Use a proper DC-DC converter to run the laptop off the vehicle's 12v rather than an AC inverter (check Dick Smith or Jaycar).

Another great site for GPS and mobile mapping is www.gpsoz.com.au
They also have a lot of the necessary cords and attachments to connect gps/laptop/pocket pc/12v
