I wanted to add my voice here as a very happy Evernote GTD'er.

Personally, I think Evernote should maintain their vision and not be swayed by a small subgroup of users ... whether they be GTDers or not. I wouldn't want another small group of users influencing Evernote with functionality that suits only them, and makes the system more cumbersome for me.

And I think one of the skills we build as GTDers is making our ecosystems work, regardless of the tools we have at hand. I don't think we have to all use the same tools .. infact, I don't think that would work. I like the freedom that DAC allows for different vendors to build or customise tools as they see fit. I've used 3 or 4 different tools for my list manager to date, and if my environment changes, I'd like to be able to switch my ecosystem.

Having said all that, I really like my Evernote setup. I don't want the calendar in Evernote ... I am sure other calendar applications would be better than what Evernote comes up with. If a vendor decides to put it in the trunk I might consider it but Google Calendar work well for me.

I have only one item on my Evernote wish list and that is the ability to navigate from a note to the related notebook.

FYI - I've written more about my Evernote setup on my blog: www.enyonam.com.
And I'll have to write a post about how I deal with dates in Evernote.
