Thom Hogan and others have been calling for camera makers to make "social cameras". The idea being that since your cellphone can take snapshots and upload them to facebook, why would you want to carry a point-and-shoot camera that can't, but that instead requires messing with memory cards and cables, etc.?
Well, the "social camera" is here: It's any camera (that takes an SD card), with an Eye-Fi card loaded in place of a normal SD card.
Remarkable and revolutionary. We've tried it, and we can report that it really works.
