I am a big Evernote fan. Got a Scan Snap for Xmas and a jot script pen. Sorry to say that Penultimate works poorly with the Jot Script. Terrible latency and stalling out. Quite unreliable. I tried changing the battery several times. Shutting down my iPad and restarting, No change. I was about to send the pen back. But, tried it with the Notes Plus iPad app. Voila! Quite close to writing on paper. This is my first disappointment in an Evernote product. Penultimate is not ready for prime time when used with the Jot Script. I trust this will be fixed, but seems a good deal of work is necessary. BTW Scan Snap works flawlessly.
