Well I'll try my ramble and maybe miss luck sides with me as I never won a single raffle that I recall participating.
The eyefi would save me quite a lot of time on downloading photos to my home server, but, now that I think about it better, the time will net zero while I try to explain to my wife how this magical stuff happens without wires.
Im sure she will think Im bonkers when I tell her that the photos I just took from the kids are already on the computer and she can share them with her facebook friends or whatever...
In any case, Im sure kids will understand how the card works faster and I will need to buy more for their cameras... and of course... eventually... wife will want hers too
Good luck to all participants!
