Interesting technology, but..

I don't see how it can go directly from my camera, out in the middle of the desert, to my Smugmug gallery. I'm pretty sure all it really does is detect that it's in range of your PC (via SSID, I guess), transfer the files to your PC, then upload them to a site. So you have to get back home before it does anything (I doubt you can reonfigure it to talk to the local Starbucks WLAN). Actually, I believe I read that it stops at eye-fi's server on the way - I'm not a fan of them having copies.

It saves the 10 seconds of pulling the card out of the camera and putting it in the reader, but the card reader is likely much faster in transferring to the PC. And it saves the 30 seconds I need to right-click/SendToSmugmug.

I also shoot everything RAW, so this is of no use to me. I typically post-process everything I shoot. And there's an old saying - a bad photographer takes 100 shots and shows you all of them, a good photographer takes 100 shots and shows you 5. I've posted an image I shot at Dead Horse Point here before. I didn't show you the 40 other angles/lighting/foregrounds/etc. I shot at that same location. I don't want everything in my public gallery. Yes, I could dump everything to a private gallery, but then I have to filter and transfer all of them to a public gallery. Seems like too much work, better done on my PC.

It sounds like my Mom would like it for casual snapshooting, but I can't see a pro/dedicated hobbyist using it.
