This.
It's a digital swiss-army knife. Right now in my pocket I have an 8mp still digital camera, an HD camcorder, the world wide web, email, instant messaging, news, social networks, books, notes, digital storage, music player, video player, gameboy, etc etc etc. You couldn't fit a single one of these into you breast pocket in the 90's - I tried, and that walkman ripped that pocket right off!
Oh snap, you mean this crazy thing makes PHONE CALLS too?!
