Here’s a clever idea – put a wifi chip on a memory card, add a receiver to your PC, a little software magic, and viola, for ~$100 you have a digital camera which automatically publishes your photos online or sends them off to be printed. It’s got pretty broad support too – everything from Smugsmug, flickr and their ilk to things like the Gallery software that I run. It’s somewhat impractical for me in that mostly the photos I publish are of the hikes and adventures I go on, where there is no wireless. While I do a good bit of ebay photography around the house, it’s not enough to make the $100 expense worth the convenience, I think, but still – slick idea.
