I also love Evernote, and rely on it for a
lot.
But even putting aside these syncing issues, it's a really terribly-designed piece of software There are so many issues with it, UI-wise, that is just bugs the hell out of me. (See note below for an example of a feature designed badly).
Still, Evernote fills a need I have that unfortunately there is no other solution for. And while it's taking a long time, it is gradually improving. So I'm still hoping that, one day, Evernote fulfils its destiny and becomes as amazing as it could be.
Note: Example of a badly deigned feature: tagging support is crazy-bad - you can tag things, and you can even organise tags into a tag hierarchy - except, no you can't, because it's only supported on some platforms. And the "support" for it is purely visual - selecting a "parent" tag doesn't auto-select the child tags, so it is basically no help. So let's go to solution 2, which is to tag things with a prefix, like "History\Middle Ages" and "History\US". But now, their generally awesome tag-completer will be annoying, since it will force you to type "History\" before getting to the point. So lets reverse tag it, like "US (History)". No, that wont' work, since you can search tags by prefix (e.g. search for anything with a tag starting with "History") but not by tag suffix. Even though, through the UI, you can do this, you can't do it with an actual search, so you can't select these tags.
