Someday we will be able to get rid of our collections of data cables and card readers -- when all our devices are wireless. But until then, the Eye-Fi SD cards are a step in that direction by adding Wi-Fi networking to cameras, so you can upload photos (and videos) automatically and wirelessly to your computer or to photo sharing sites.
Eye-Fi added video uploads in March, along with a 4 GB card and a free iPhone app (see previous post). And now the new Eye-Fi Pro card can upload even big RAW image files (along with JPEG photos), plus supports Ad Hoc networking directly between a camera and a computer, even without a wireless router.
In addition, Eye-Fi has added a new Selective Transfer feature for all of the Eye-Fi cards, so you can mark only selected photos and videos to be uploaded, using the "protect" or "lock" feature in the camera menu. This is a new free option in the Eye-Fi Manager software.
The Eye-Fi line starts at $49 for a 2 GB card that connects over your home network, then adds cards to upload to online sites, support video files, geotag photos, and support Wi-Fi hotspots (these are also available as add-on services). The new Eye-Fi Pro card with 4 GB adds the RAW format and ad-hoc networking, and is $149.
