I would agree it is a poor decision to buy a NAS simply as a replacement for Evernote but that is not the reason most people buy a NAS. People buy NAS's for a number of reasons besides note taking and updateing hardware every 3-5 years is pretty standard practive as technology evolves. Besides, NoteStation is not tied to the hardware. The data exists in a database which is stored on your drives and should be easily moved to your new NAS. I imagine at some point you might even be able to access your NoteStation notes outside of the NAS environment allowing you too move your data. Who knows.
