Hi Jim,
Here's my reasoning behind being an Eye-Fi advocate (or wireless transfer in general).
With the amount of pictures I take I find myself cycling between my two tiny Fuji-sized batteries every five to seven days. I know I can extend this by dimming my LCD screen. It's on the bright side now. I can also be more careful with how long I leave my camera on while waiting/composing for the shot. My flash rarely gets used unless absolutely necessary. I'd rather go for longer shutter speeds and brace the camera or myself against something steady.
Compare that to the at-least-daily cycling of the SD card I would need to do. The camera contacts would feel it and so would my computer's built in reader. Sure, my battery would stay put and it would stay put for longer than five to seven days since there is less drain. However, the trade off with extra SD card cycling seems "expensive" to me. I see how sturdy my battery looks in comparison to the near-paper-thin SD card and I want to leave my SD card alone as much as possible!
I know, I know... there are a lot of smart engineers who did a lot of design work to get the number of SD card cycles up in the thousands and tens of thousands. I'm sure I'll toss my Fuji into the trash well before anything wears out.
I'm also not so keen on handling a small SD card. My dexterity is poor. It's ironic since I have pretty steady hands.
Personally, I think the future lies in wireless transfer with physical transfer as a backup. I thought Panasonic and Samsung are already starting to do this. Its very convenient. Let the electronics do the handshaking and transfer. If that fails then you should be allowed to take the card out.
Digressing, I thinking that chargers will one be wireless one too day (not tomorrow). They will use induction charging with physical connector backups. Just set your camera on a charging pad overnight while you sleep.
If a company can do all of that then it would be possible to have a truly sealed camera!
