I've been running the Office 2010 beta release and really enjoying it but not really USING it. Especially Word. Most of the time, I do Word at school (work), and not much at home.
So I've started out by writing some blog posts – this one and the one on Outlook 2010. Frankly I prefer using Windows Live Writer to blog, but this isn't bad. It doesn't have some special commands for blogging.
I do like the file recovery – I have a blog post that isn't showing up for some odd reason, and I had already closed the entry without saving. It was very easy to recover it.
There are lots of nice templates, which I hardly ever use. When I do a word document, I am almost always writing some documentation. Especially now that I've got most of the people in my building at least knowing they need to read email. I hardly ever write a memo any more.
