Well, there is finally a version of
Evernote for the Mac, albeit a Beta version. If you haven't signed up for the beta, now's a good time.
While not perfect, the developers have done a good job of Mac-ifying one of my favorite Windows apps. The new version of Evernote is ambitious - Evernote is attempting to go multi-platform, and I'm not just talking about Windows and Mac. There is a web version, as well as mobile flavors. This one of the first total solutions that I've seen for a consumer-level unitasker. When I refer to Evernote as a unitasker, I don't mean it in the pejorative sense either. It does its one task very well.
A welcome piece of functionality to the Evernote puzzle is tagging. While I would only say that the tagging feature is in its infancy, it is definitely a major step ahead of the hierarchical categorization of its predecessor.

On the Mac, there is no shortage of competition for Evernote:
VoodooPad Pro (which I own and use, but not nearly in the same way that I use Evernote on Windows),
Yojimbo (I'll leave it to the Mac zealots to wet their pants over BareBones' apps — I am not a fan) and
DevonThink (I think I have a license from a previous MacHeist, but I was already using VoodooPad) are no slouches in the note-taking realm. While some may arguably be better than Evernote as
Macintosh applications, none of them are cross-platform, syncing applications. A key distinction for any Mac user who lives in the
real world.
A lot of Mac users among us are multi-platform computer users, with most of us being Windows users during the day, and Mac users the rest of the time. Plenty of us have non-iPhone smartphones also. Evernote makes a serious effort at bridging our multi-platform needs, and I commend them for that.
I've been using the Evernote Beta for the Mac, and I'm ready to say goodbye to VoodooPad. I've been waxing evangelical on Evernote for over a year on Windows — the free version is an indispensable tool for business. Now that Evernote is going to be a syncable, multi-platform application, there is good reason to pay for that premium feature.
