I'll also have to agree with the warnings about upgrading. The most immediate difficulty I'm having is eyestrain resulting from the tiny grays scale fonts and oddly contrasting panels. I'll admit that Evernote 5 is pretty, but it's not something that I can attempt to read for more than a few seconds at a time. This may be what ends up forcing me back to an earlier version for now. A second issue is search. Searching on a combination of tags and then text was very easy in the earlier version. I could click on a tag in the side bar, type some text in the search window and quickly focus in on what I needed. I select a tag now on the side bar (where I added them), type some text, and the tag part gets thrown away. Yes - I can type "tag:name" into the search field, or select with the pulldown in the search box, but both are very clunky compared to Evernote 4. I also used to be able to selectively remove/add search terms. That function appears to be gone as well. Overall, search went from the very best (for me) feature of Evernote to something that feels very unintuitive and awkward.
