I’ve long had a soft spot for Evernote. I’ve been using it since it was a Windows only app that used an “endless toilet paper roll” metaphor for its note taking. It has come a long way, and this is a nifty integration for it. We use Skitch a lot for UI reviews and explainers.
While I still use Evernote for most of my personal stuff, our recent adoption of Office 365 has me “all in” on OneNote. The full blown version of OneNote is pretty awesome if you use a stylus — something Evernote hasn’t fully integrated yet. I’ve pretty much become a total convert over the course of the past week.
