So I'm using Office/OneDrive online and the web versions of Word/Excel. The reason I don't use Google Docs is that I think the UI is inferior to Microsoft solutions. And I'm pretty sure they are DOM based (for the most), In fact some Excel operations even execute a server round trip. Google Docs is nice because of the addon ecosystem that AFAIK doesn't exist with Office 365. But I don't like the editors as they are inferior versions of Word/Excel... Also why is it so hard to produce or edit PDF files online still today, or fill PDF forms online? Neither Google or Microsoft provide that fuction. And no, I don't want the PDF file to be converted into some Word like file, I want the PDF to keep its layout/fonts...
