I've been using the software for a while, and I'm getting used to it, but to be really honest I don't think Office has been the same since it lost that familiar menu bar.
The 'ribbon' look just isn't as intuitive in my opinion, and it smacks of change for change's sake. In the never-ending quest for a way to maintain the revenue stream Microsoft has to produce these new Office versions every two or three years, but for the average user there's nothing compelling about Office 10.
You know, I never thought I would hear myself saying that. Perhaps there'll be some dramatic changes before the software goes to shrink-wrap.
