From what I see of 2013 it looks a lot more unusable than 2010.
2010 is bad enough, everything you do is a clickfest.
Gone are the days when you could click a button for a new document or to print, it's all click, click, click, and for printing, "yes, I do want to enable effin' printing"
Since we updated to 2010 at work some jobs take me twice as long
Productivity is critical for someone who works in finance and uses Excel all day.
Oh, you can modify your toolbar - at home. At work the toolbar reverts to basic everytime you logon (or at least it does where I work).
At home I'm sticking to Office XP.
