I bloody HATE Office 2007. It's the least intuitive and annoying piece of shite ever. Not to mention that you have to make an effort to save every document as a special file type just to make it readable by anyone who doesn't have 2007. This isn't really new, but between 97 and 2003 they had managed to keep it consistently compatible without any special tricks. Bastards.
Glad you have a new shiny though! I haven't upgraded my Vista (*spit*) machine to 7 yet because I haven't had time- even Mama is ahead of me there, although she cheated by getting Karen to install and set it up for her! ;)
