Why Are Quick Notes Useful?

Apple
For most people, taking a note, or saving a link, is a statement of intent.
You might plan to access that note later, but its likely that youll never find it.
Or, if that note contains information form the internet, its probably easier to just Google it again.
What Quick Notes brings isthe notion ofcontext.
Notes appear when you need them, not the other way around.
This combines with another new Notes featuretagsto make organizing and finding stuff easy.
These tags even show up in the global Spotlight search.
Imagine this in read-later apps, or your PDF app, or in an e-reader app.
For instance, theres no way to use the same quick note across different sources.
Say you clip some text from a web page about a holiday rental apartment.
This creates a Quick Note.
Then, you discuss the apartment in a Messages thread and check it out in the Maps app.
This creates two new Quick Notes.
Support is also spotty.
Still, Quick Notes might radically change the way we organize information.
