I'm using Evernote with wine as well and its still buggy. The best option I have thus far is to install virtual box and run a version of windows, then install the windows version of Evernote. Evernote works great then, but the obvious problems are the high use of resources and the disjointed OS (between linux and windows).
I have been looking for a full featured port for Evernote to Linux and at this time I don't think there are any really good options.
NixNote and Nevernote both suck in my opinion. So feel free to try those, but I was certainly was not impressed.
One other option is to install as many browser plug-ins as you can for Evernote and something close to the same functionality. Again, not a great solution, but its what available at this time.
If anyone has any other ideas I would love to hear them, since I'm in the same boat here.
