I'm still on 8.5.  I have 2 questions for X1 users...

1) Don't you still have to re-learn a lot of what you already now from 8.5?

Yes, it took a bit, but it was worth it.Seemed so right away.

2) It still seems that many many things take more keystrokes that in 8.5.. is that still true

No. At first sure. but I'm with a lot of other people it's the keyboard shortcuts. I never used them much before, now having seen simpler, easier to remember types, and plus I've made some of my own too, they are the way to go to keep the clicks down to an acceptable level. Not having all those buttons forced me to adapt, so now instead of remembering under which button to find what I'm looking for it's which shortcut.
