It looks nice. I will give it that, but $5 bucks seems a little much for a notes app that can't sync across platforms as far as I can tell... not even iCloud. Evernote, Springpad, Simplenote, and even Google Keep for iOS (when it is finally release) have syncing from the get go.
I certainly don't see much reason to buy v1.0 for full price. Wait a month and see if the features improve or the price drops.
i predict that features will not improve.
i predict that another app will be released, at a similar price-point, with more features.
and then another one after that. and another.
in other words, i predict a well-executed plan to extract as much cash as possible from fans.
nothing wrong with that. if you can get away with it.
