One of the major problem with digital cameras is the USB connection cable that you need to connect to download picture. If you are a lazy and unorganized like me, most of the times you will end up looking for that cable for hours.
Recently I came across http://www.eye.fi/ website and saw the product online. Afterwards I ordered it on Amazon and got delivery in India in next seven days. Landing price of the eyefi 4GB card was approximately 2.5k. Eyefi package had 1 4GB card as well as one USB adaptor to configure eyefi card. Configuration was easy and eyefi card worked like a charm.
In no time I made my digital camera wireless . No worry of connecting those irritating USB cables from camera to PC neither you need to wait till the time you connect the cable. The moment you click a pic, it gets transferred to picasa/PC or any other social sites. Some of the many features that I could observe were 1) ease of sharing 2) ready accessibility of pictures on PC 3) No worry of sharing pictures individually on each social site.
