I've been using Evernote on and off for 5 years now. The Windows client keeps getting more and more useless features, but basic performance remains terrible. These days, I have a beast of a machine compared to 5 years ago. The performance is no different. It is not uncommon for simple tasks to lag for 30 seconds or more. Want to create a new note? Be prepared to wait 30 seconds. Want to create a stack of notebooks? Wait 1 minute. Folks, you have my faith in the integrity of the data you store. But my god. FIVE YEARS is not enough time to make a windows client that works nearly instantly? I always end up trying to use the software for note taking, but it's just too slow. It's faster for me to write something down on a pen and paper, and now that I've moved to Microsoft Surface, I've found One Note to be infinitely better for actual note taking. If Evernote is just going to be a place to store old documents, why keep adding all these useless features? Why not just perfect the core functionality? It's mind boggling. I have not tried to use the Windows 8 Metro version, so I will give that a go sometime. But man, very frustrating.
