I have used sharing/editing Google docs in the past (Not in a Hangout and on a limited basis) but it leaves little to be desired and seems geared more towards documents/presentations, etc. Not very dynamic. I guess I enjoy the flow of G+ and Springpad and see where they could compliment each other more.
For note taking I have tried +Evernote
(Heavily) , +Catch (limited), and now +Springpad
(Just Started recently because I was looking for "more" due to some of Evernote's annoyances) , and I see many ways G+ can gain from Springpad.... I guess for now I'll stay with multiple services (which doesn't bother me one bit).
Have you tried any of the note taking apps mentioned above? What are your thoughts on each of them? Are there other ones you have tried that you would recommend?
