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.<p>So for a 'novelty' app with no marketing, it doesn't seem too bad.<p>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.
