Interesting idea for an app - is there a huge market for this? The biggest parking lot I ever have to worry about is Disneyland or the airport, and I always just snap a photo of the lot ID. Before I had a camera phone, I just wrote it on a slip of paper and put it in my wallet.
So for a 'novelty' app with no marketing, it doesn't seem too bad.
I also just got the Droid, and I'm seeing a lot of "updated for droid" or "not compatible with droid" comments. No doubt the Android platform will open a much broader market, but like the PC, you have to worry about more hardware.
Car finding apps is obviously not a HUGE market that you would want to start a business around, but there clearly are people out there looking for these kinds of apps. I occasionally get emails from users telling me that they've been using it for different purposes, like Geocaching games.
With more phones coming out, on thing Android developers are starting to have to worry about is making sure the app works on a variety of different screen sizes. I guess it's a necessary evil to have to deal with.
