As someone who had a 20yr break from MS software until a recent new job, I'm not sure it was Google who demolished Office.

I reckon it was MS. I can't believe how confusing/confounding/frustrating the modern MS Office and it's cloud integration is. I swear Office 2003 was miles better. And it seems that way with the UX of just about all their stuff now.

I would run into little functionality limitations/frustrations with the Google suite, but I wasn't prepared for how far ahead the UX is compared to MS tools.
