is more a challenge to Android than IOS. WP7 is unbelievably stable. Many people report months without ever rebooting. The main advantage over IOS is a more streamlined integration between Apps, processes, etc. In IOS everything gets siloed(sp?) into separate apps. Each app is its own island. Its hard to explain the difference without using, but the more you use it the more you see it.

It doesn't have the same volume and in some cases quality of Apps as OS, but I've found it to be sufficient so far. All the apps I used in Android are there.

If you like One Note/ Office/ Skydrive, MS has very good integration there. I love taking a picture in my phone and having the image show up in a skydrive folder on my desktop a few seconds later. Very handy. I am also a big One Note fan, so using the best mobile implementation of it is nice.

Looks are better too. The WP7 is comparably fluid, if not more so, than IOS. The look and animations are interesting and fun to look at. Well designed Metro apps are a joy. I've never seen anything that matches the Facebook app for example (which I see you don't care for much).

On a personal note, I detest the father knows best attitude that Apple approaches technology with. I know it works for some and I can appreciate that, but for me, I always feel like I'm renting Apple hardware and using it with their permission rather than doing as I please with it. I'd always feel like I was cringing under the ban hammer if I ever did anything so horrible as root my device and tether it.
