Smartphone/Pocket PC Mileage software

Just found out about this new software for Windows Mobile devices (Smartphone or Pocket PC) that among other things allows you to keep records of gas purchases (gallons of gas, price/gal, odometer reading) and automatically calculates fuel economy, fuel consumption rate and cost of ownership value. I've just downloaded this from Two Peaks and have just been playing around with it - so far looks promising. At least may mean that you can enter the data into your phone/PDA at the pump and save having to keep a pile of receipts. Syncs with your desktop so data input doesn't HAVE to be a pain in the butt and keeps a nice history for you that you can port to Excel if desired (nice!).

It also can keep track of other expenses than just gas and can alert you for scheduled maintenence - but the car can do that so no big deal.

Thought some of us might be interested since we love discussing MPG and being able to pull out your phone to show non-believers just sounds too cool.
