I am a huge fan of the new Evernote for iOS. I think it's much improved over the previous one (which was only a few months old). I think it's much more usable and it finally added the ability to manage stacks on iOS.
The only thing I don't love is the addition of the 'Announcement's and 'Market' sections. It's not that I dislike these areas completely, but I feel like premium users should be able to hide them.
