Windows Phone Thoughts: Do You Use SMS On Your Windows Mobile Device?

I was wondering how many of you used SMS on their mobile devices given Windows Mobile has other communication methods like email, IM and a variety of others that you could install. My wife and I use SMS several times a day. It is a good way to keep each other up to date on what is going on, but when it comes to other people I know in North America, SMS is not very widely used. I know it is a much bigger deal outside of the US and Canada, but it is also very costly to do a lot of international SMSing. I am not going to bother asking about MMS. You can be the biggest MMS fan on the planet and if you can put up with the MMS client on Windows Mobile devices, you have a strange predisposition to self-inflicted torture. 8O

Note: If you are using SMS as "push notification" for pre-WM5 MSFP devices, don't count that.
