The SD card inserted in my HTC phone again opened my horizon. GPS with all European maps Photos HD, almost unlimited video recordings ... A library on hand, etc. And what a comfortable reading and writing !! Prior to use some applications I am constantly changing my card, with the risk of losing data, map and even the phone. Now I no longer touch. While a backup of the SD Card on a PC is longer than before, but that's the price to pay for 32GB!
