There are plenty of cameras that send their photos to your phone, but you frequently have to transfer those pictures yourself -- and it's another hassle to get the pics to other devices. Eyefi thinks it can solve these headaches by launching its own online service, Eyefi Cloud. If you're using one of the company's WiFi-equipped Mobi cards in your camera alongside new Android and iOS apps, any photos go both to your mobile device and Cloud right after you've hit the shutter button. You only need a browser to manage your shots, so you're not stuck if you want to see your photos on a new PC.
