"Although Google Keep is a cool web application, and offers a native Android app as well, it lacks text formatting feature and the simplicity of Scratchpad. Keep is not a perfect replacement for the Scratchpad."

I can't say we really lost much seeing as Scratchpad is just an app that uses the Google Drive API, I'm sure someone could make a replacement if needed.

Hopefully Google will make Scratchpad open source if they haven't already for the people that prefer it over Keep.
