I use Evernote on my PC and iPhone and have never had problems syncing between them or displaying notes before. When I had the email from Evernote about the brand new version there was nothing to make me think the Win10 version was only a work in progress: it was presented as a new, shiny, all-singing, all-dancing version. I've been using Evernote for years and have never until now regretted my choice.
