I play only 1 game on my iphone - shadow era (which is excellent for wiling away those spare minutes). However, it drains my battery quite quickly, so I don't do it that often.
Some other uses for my iphone besides surfing internet/checking email and the like.
-dropbox and evernote allow me ready access to critical work-related files. It is great being able to whip out my phone and show that document to a colleague without having to boot up my laptop (or if I am outside without access to it). It's no ipad, but it works in a pinch.
-keep track of all my news. I used to spend half an hour on the comp each morning before work (4s is my first smartphone). Now, I can do it while walking to my workplace, a great time saver.
-airvideo lets me watch shows at home
-runkeeper for keeping track of my jogging progress. I even used its mapping function in class to explain the concept of perimeter and distance. (I am an elementary school teacher)
-in class, I can use it to keep track of postings on blogs. I find the wordpress app makes this easier than if I keep refreshing the page.
-mobile mouse as a remote clicker
-wireless hotspot to tether my laptop to for the odd occasion my school network is down
-pages in theory lets me do simple word processing, but in reality, I find the small screen makes it extremely difficult. Still, I have used it to make minor changes/updates to emailed documents when I am on the go.
-I can remotely access my home computer (but I need to call my mom to switch it on for me first).
It can do a lot of things. You just have to be willing to explore its capabilities and be creative in some cases.
I say I am getting my money's worth.
