Completely agree. I try not to use it but don't really have a similar replacement. For some reason there are tons of notes apps, but the ones that kind of resemble keep fall short of the easiness and practicality of it.
Right now I'm just waiting for Quillpad to add sync capabilities to see if we are finally there.
There was a thread on the android community recently about that, I think. If you want to dig through there. I think the consensus though was that it is pretty hard to replace.
