We already thought the Eye Fi Wi-Fi SD card was so good it seemed like it was dropped upon us by an advanced alien civilization. Now the company's made it even better, speeding up the new Pro X2 with Wireless N connectivity. Take your pics, blast them even faster from camera to PC with no wires in sight — we like.
Beyond that refinement, there's now a clever capability called Endless Memory, erasing pics once they're safely transferred to a PC, making it seem like the little 8GB SD card is limitless. If it didn't cost $150, we'd get two.
