If you use the latest version of Chrome for browsing the web on your Apple iMac or MacBook, you will have noticed a new icon in the menu bar, a bell icon which is used to access notifications and Google Now. When Chrome is running, and it doesn't have to be on the screen, it can be minimised, clicking this icon will display a notifications panel that is similar to what you would see on an Android phone. Is it useful? Do you need it?
When you are working on your computer or simply browsing the web for fun, you will occasionally need to temporarily store information. One way of doing this is with the Notes app or Stickies, the Mac's sticky notes app, but Google Keep now runs on the desktop and it offers several advantages over the OS X built in apps.
