It depends on what you're signing. My letters of authorization to my bank require a "wet signature." Scanned or photographed and emailed is fine, but they want you to print and sign, and they've sent it back to me when they can tell I've used a digital stamp.

This product looks interesting, although the idea of me entering coordinates for the stamp instead of just stamping it in a GUI is not at all appealing...
