I've just got an Eye-Fi Pro X2, great for wireless transfers to my laptop or tablet. JPEGs pop up on the screen as I take each shot, not as fast as a wired tether, but love the freedom of having no wires. Being able to review the image on a larger screen is priceless. I use my home wireless network to speed up the transfers, but the card can generate its own wi-fi anywhere. I drop the JPEG size in camera down to small to keep the file size down and keep the transfer quick. You can also transfer the RAW files, but I don't see the point; I just pull them off the card at the end of a shoot.
