I like the idea but I think there is more potential that could be addressed here.

A calendar is clearly useful --- but you don't really need it *all* the time.

What to do in the meantime? How about display personal photos?

Basically, I'm talking about a digital photo frame *with* calendar. I've looked and found one or the other --- but why not both in one device?

It doesn't look like it would be all that difficult to produce. The calendar could be just another graphic file but one that is displayed only on demand.

I think there is a real marketplace opportunity here.
