48Gb of mass storage available in my pocket with no drivers required. What's that all about? I miss the days of carrying a CD of driver software.

Tethering my laptop through it for internet access over my unlimited dataplan - now I have too much money to worry about.

Replacing my smartphone, iPod, video player, TomTom, Nintendo DS and point-and-shoot camera with one beautiful device. Why can't I carry six things with all the associated chargers and battery issues.
OK, so maybe not the TomTom... yet.
