>Nothing to stop you. You can use Isolated Storage, XML, etc. But, IMO, WP7 is currently targeting personal use, not business use, so a DB isn't as important. I'm still seriously considering getting a WP7 phone when available, but am holding off final decision to actually see the available devices, purchase costs, and service plan costs.

I could write the app in binary I suppose, but somehow I got used to having a useful programming environment over the years. This sounds like as much fun as making a useful grid in MVC 2.0 (I see they have something *NEW* in MVC 3.0 *beta* that is supposed to be a grid - can you imagine?).
