with the iphone and ipod touch it isn't that is it has lots of features (which it does but...) it's how easy it is to use. Currys have got an ipod touch demonstrator and when i tried that having never used an ipod touch before I knew what to do within 2 minutes. They are so simple and easy to use. That is why they are so popular. Hell i've got pretty large fingers and 97% of the time the tiny ipod touch virtual keyboard is fine. (and by large fingers I mean take up more than one key on the ipod touch.
KILL IT WITH FIRE. BURN IT. MAKE IT MELT. SMASH IT. CRASH IT. BLOW IT UP. CRUSH IT. MUSH IT. PUSH IT. SHOOT IT. BOOT IT. CRUSH IT WITH A TANK. SHOOT IT WITH A ROCKET. PUT FIREWORKS IN THE FUEL TANK. BLOW THE THING UP.
