- Create a workout on my laptop, then walk to the back yard and follow it on my phone while taking additional notes.
- Create a packing checklist for a trip on my desktop, then walk around the house with the list in my hand, checking off what I have already so I know what I need to buy.
- Scan a tax form to my Taxes notebook on my phone and then go back to my laptop where I'm using Turbotax.
Evernote has worked for these use cases for a long time.
