I use it for plenty of shit smiley, it's made me use my computer less.
Just a small list:
- track and read all my websites
- manage my email exclusively
- track my fitness - GPS data, calorie and diet tracking, running podcasts etc
- as a camera for quick snaps
- personal organiser
- virtual punchcard for my office
- GPS with all local business information
- all my banking
- weather and watch
- watch movies and tv on the go
I was definitely in your camp about expensive phones being a waste of money, now I have one I can't imagine living without it. It just makes my life easier
