Just tried out and am really impressed with the entire setup and pairing process. Very clever use of QR Code. It works just as featured in the video. The 2-3 second wait for uploading/processing is annoying but I can get used to it. However, having to click 'Done' disrupts my chain of thought and makes concentrating harder. I don't think I can get used to manually clicking 'Done' after every other sentence/paragraph. I wish there was a way you could auto-click 'Done' when my sentence was completed.
A neat UI could be a buffer that slowly grows, maybe showing the # of seconds recorded. Once it's near 30-60s length and I pause for 1-2 seconds OR shake the phone backwards, auto-click 'Done'.
Also what does the "Log Dictation on Desktop" option mean?
