At least for this Bob here: 1. The ribbon interface has more levels of depth, which equals more clicks. If most of your commands are in the same toolbar, you can have a lot of commands that are only one click away, even if you don't customise. For example, to "insert symbol" in word to get an em dash or non-breaking space or similar, you have to select the insert tab, click the symbol dropdown and then "more symbols ...". Used to be one click on the "omega" button, or two via the menu (insert / symbol). The fact that I have to move the mouse from one end of the screen to the other and then half the way back again also doesn't help. 2. Maybe this is just me but Alt+N, U, M for "insert symbol" is a lot harder for me to memorise than "the button with an omega up there to the right". It feels less intuitive somehow - I really like working with visual muscle memory (if that's a thing) where I remember the place and shape of a button. 3. Customisability. Yes you can do this to some extent with the ribbon, but in Excel you can't just swap out "merge and center" with "merge across (but do not center)", you'd have to replace the whole "section" - I've tried. 4. Speaking of visual muscle memory - the number of times I've come in to work and found that my ribbon has changed in an update overnight. Some of these are work installing new plugins, but most of it is microsoft adding new "features". No thanks, I don't want my documents "integrated with LinkedIn" when I'm working to a deadline. 5. There have been several major changes to how the ribbon looks and works as Word has gone through new versions since it was introduced - in a lot less than 17 years. Of course that happened with toolbars too (I think around 2000 everything went "flat style", but you could at least turn it off), but I found it easier to adapt back then. Maybe I'm just getting old but each new version that comes out feels like learning half the things I need for work all over again.
