Good general notetaking app, but missing important elements (to me)
The client is prone to random crashes, tables dont paste well from external sources (e.g. websites or the command line), it completely lacks support for equations, and the "code" text style doesnt work. These problems are showstoppers for me: my notes are comprised almost entirely of equations and code, or tabularized results of my code.
To its credit, Outline looks good, is fast, and is an improvement over Onenote in the way you organize tabs and sections. Dropbox sync is a nice addition as well. If you arent using it for code or math, its still a good notetaking app, but in its current state I dont believe it is worth its price.
