@matigo I'm stubbornly on the original flavor of Notational Velocity, and the main thing I love about it is the speed and lack of features beyond being the best possible writing/noting/jotting application it can be. Sure, there is a built-in sync with Simplenote, but that's about it.
Blazingly fast search is a huge boon for me too, as I tend to go looking for old notes from time to time. So far, Notational Velocity makes this dirt simple, besting anything else I've bothered testing so far. Combined with the ability to use the whole thing without leaving the keyboard is quite lovely. I haven't even felt the need to look at any alternative for… years. :D
