Eye-Fi are the people who make digital camera SD memory cards that send the pictures you take directly to your Wi-Fi-enabled computer, or alternately to an online photo-sharing site like Flickr. In other words, they're for people who are too lazy, or technology-challenged, to actually take the damn card out of their camera and stick it in a card reader to offload or print the pictures. (Or they don't shoot in the higher-detail Camera RAW mode, which the JPEG-only Eye-Fi's don't support. Boo.)
If you're one of those folk, God have mercy on your…er, Eye-Fi's got two new cards for sale. The 4GB Eye-Fi Share (which, at US$79.99, doubles the capacity of the 2GB Share for only twenty bucks more) does the home PC/photo-site thing, as well as sending video clips to YouTube. For another twenty clams, you could score the Eye-Fi Explore Video, which adds geotagging info to your snaps/vids and allows access at Wi-Fi hotspots.
Right now, both cards are pre-order items. Also pending: an iPhone app that'll share your handset's pictures with all those Web galleries, and it'll be free…um, to Eye-Fi card owners, that is.
(Oh, and that uproarious noise you hear in the background? That's our pro-grade Canon DSLR's pointing and laughing at the Eye-Fi.)
