I've been using Eye-Fi cards for a while now, and have a more generic one as well. They are kind of neat, but the issue is it can take a while to transfer the files. Pulling the card and plugging it in is still much faster, and uses less battery life on the device.
Since I've gotten a Galaxy S5 though, what surprises me is how well the camera on the phone works. I find I tend to just us it any more. If I was traveling, I could even see not taking my DSLR with me and just using the phone. I've got it set up to automatically upload files to the cloud whenever attached via wifi.
