I always wanted a lightweight and more-or-less-trustworthy notebook service and it's exactly what this cuteness delivers. It understands all necessary formatting markers, the extension is great, and it even works well, - which I didn't expected at all after the phone app refused to work for two months shortly after it's announcement. You can't insert images though - at least for now - which is really sad, although understandable. Standing by for updates - I really could use some more powerful formatting tools and images.
