It sounds like you work for Microsoft. I'm not accusing you of being a shill or anything, your post just sounds like it was written by a marketing department attempting to sell Office to the /. crowd.
There was a time when I had to fire up Office because of various formatting quirks or whatever, especially when it came to Excel, but it's been a long time since that's happened. If you believe that LibreOffice isn't good enough for 99% of users out there then I doubt you've used it recently. Using the Gimp/Photoshop comparison is ridiculous (even though I use Gimp for all my photo manipulation needs; I'm not a photographer or graphic artist but I do occasionally need/want to create images or manipulate pictures).
When it comes down to it text editors, spreadsheets, and presentation programs have hit their ceiling when it comes to desired features. They're like Vise-Grips. There was a time when you had to get the name brand ones because nothing else worked as well. Now you can find knock-offs that do the same thing. A couple x-mases ago someone gave me a set of these Kobalt things that were supposed to be like Vise-Grips but easier to use and fancier. They were a pain in the ass and I never use them. That's what Microsoft did when they rolled out their ribbon interface and this 365 crap. They tried to put bells and whistles on something that didn't need them (for the sake of continuing the upgrade cycle) and made an inferior product. LibreOffice doesn't just work as well as MS Office, it works better.
