At our company, we have been using 2010 beta since it became available. I find it easier to use and control the project than 2007. I have reported some serious bugs that would render the software useless if not fixed but I have also learned the workarounds. Therefore, this time I think we will be earlier adopters. We are a smaller shop by that I mean we have 4 project managers within the company but each is working in their respective area (Engineering, Marketing, and IT). If the initial release of 2010 has most of these serious bugs fixed , than just back up your work often because 2010 is still better than 2007.
