Ed Fries (then at Microsoft) was the guy who spearheaded Microsoft Word to beat WordPerfect:https://www.youtube.com/watch?v=Od_kGGW-Xq4
And as he explains, when he leaves the Office division to work on the Microsoft games division, the management was disappointed (however I'm grateful because he assisted Ensemble Studios with Age of Empires and a bunch of other products). What's interesting about it all though, is how Ed explains it was easier for him to work without 'excessive management' when he moved into the games division. It wasn't seen as a lucrative division, so he had free reign to do whatever. Of course ONCE it became successful, then management hounds down on it (just like when the Office division became successful).
Here's a bonus video where he talks about why he left Microsoft:https://www.youtube.com/watch?v=YkTIE2EHfpY
Julie Larson-Green doesn't have experience with computer products like Ed Fries, and probably doesn't understand the historical challenges with WordPerfect and Lotus. And if you don't understand those historical challenges and why certain things were designed a certain way, you'll make [wrong] decisions.
On that note I quite like Office 2007 (however I still use PowerPoint '03 because it has some graphical features that were removed in 2007 for whatever reason... thankfully they can be installed side-by-side). But quite honestly, I loathe Office 2013. It takes longer to load than any other office, the interface is horrible, aaaaand... customization features were removed that *were* present in 2010. Why?! Why remove features that people have used, like the visually impaired (there was a whole thread about people who increased the font size in specific windows of Outlook 2010 couldn't do it in 2013 anymore).
