This is a great use of your cell phone's camera for the holiday season, since many people go out to dinner, parties, and drink wine while out. There have been many times where I tasted a new bottle of wine, decided I loved it, and tried to remember what it was called so I could purchase it later.
I never remember. I blame my bad short-term memory and the actual wine drunk.
So now I have taken to snapping a shot of the wine's label with my iPhone or BlackBerry. Now I never forget my new favorites!
