Smartphone. I hardly ever make calls with it though. Or text. Until I got a smartphone I hardly ever used a mobile - just kept it in the car for emergencies. My smartphone changed all that though. It provides me with all the music I want, several books to while away the odd ten minutes, sat nav, half way decent camera and the ability to browse the web while on the move. Several times while out walking I've wondered about a monument or bridge and now I can find out then and there.
