I bought my one of these brilliant little devices a few years ago to make it easier for me to send photos videos and music between my pc and my phone. I don't know how I lived without it as its a fantastic piece of kit. Depending on the phone you have you can even use it to control your pc remotely which is always amusing when somebody else is using it and you make it look like the pc is haunted :). I would highly recommend a device like this for sending data about as it makes bluetoothing new music to my phone a breeze. When you need to free up some space on your phone with things like high definition videos clogging up your memory its great. Even if you need to leave it on over night for gigabyte's of sata to transfer it gets the job done 10 out of 10!
