What do you like best?
I love google Keep! Since I discovered this service, I can no longer live without it. I use it for everything... Take a general note on the fly, write some job notes and sharing with collegue, create a reminder and so on.
The service allows you to assign a label to the notes, (so you can find it immediately) assign a different color to them, or pin the one you think its the most important.
Last but not least It's totally free
What do you dislike?
I personally think that it would be very nice if the service had more functionality like: more customization (new colors, the ability to format the font, etc..), more type of note (vocal note, video note, import/export feature, etc). A dedicated support for the serivce.
Recommendations to others considering the product
Google Keep it's for me a really good service for take note and reminder with some customization and some nice feature like collaborative share. It's free, it's a google service and this means security and reliability as well as excellent accessibility.
What business problems are you solving with the product? What benefits have you realized?
With it my company can finally share collaborative note on the fly, in a fast and nice way. It's difficult to find someone, nowadays, does not have a google account, and this facilitates access to the service saving time (and money).
