Pros
Pro Unlimited and seamless sync across all Google connected devices, from mobile to desktop
When a mobile device isn't in use, Google Keep can be accessed as a Chrome app or as a website. Basically, no matter the device being used or the OS on it, there is always a way to access the app. There is also no limitation to how many devices this can be done with, freeing up the user to always have access.
Pro Super fast to use
The focus on a minimal interface makes everything fast to use on both web and mobile. This comes in handy for when a note needs to be jotted down quickly as there is little to no load times or faffing about trying to get to a space where the note can finally be recorded.
Pro Includes character recognition for text in images
Google Keep lets users take pictures of physical notes and makes the contents searchable within the app. This can be a convenient time saver for those that do not want to type out the necessary info, but rather take a quick snapshot of it.
Cons
Con No desktop app
The web app is slow and insufficient, requiring constant internet connection and a browser all the time. The UI is not optimal for use with a keyboard and mouse, everything seems to be optimized for touch and mobile usage exclusively. It is really inconvenient to have to open the browser every time you need to get data in or out or to quickly consult information.
Con Does not integrate with Google Calendar or Tasks
It does not integrate with Google Calendar or other Google Apps with the exception of "Google Now."
