Does anyone know what the resolution of the TV Sharecam is? It seems like a pretty neat little gizmo, but my concern is that the resolution's only 640 x 480. Also, what's the maximum size SD card it will accept? Is it limited to 32MB, or will it take the 256MB or 512MB cards?

It's VGA (640x480) resolution according to this page. The only difference it seems over other cheapo digital cameras is that it's got a composite video output and uses SD cards instead of built in memory.
