I guess it's all a matter of personal taste. As a fairly heavy user of MS Office at work, I absolutely detest Office 2007. My productivity dropped dramatically when I started to use it, mainly because I just could not find many features that I use regularly. I think Microsoft has spent a lot of time making Office 2007
different to previous versions to help sell upgrades, but they forgot to actually make it
better for most regular users. On the other hand, I was able to switch to Office 2008 without any real pain.
Anyway, this is very off topic! I'm looking forward to giving Crossover a try
