I was restructuring my notes the other day (thousands) and the 50 note limit message popped up. It got me very scared. For me it’s a classic scenario when I decide that a bunch of tags deserve their dedicated notebook. it’s a good thing the legacy version is still around, and in fact I keep the last old version on a second computer so when the time comes I will be able to migrate out of evernote with limited pains.
I must say that v10 2 years on is fairly stable, on the Mac, but still slow as hell. The iOS version is still unusable.
