You are about to fly for a vacation and realized you don’t know enough about your destination.
Sell small cheap tablets at airports that have comprehensive written and video information about destinations, plus a GPS navigation software. You pick up the tablet with your destination or have multiple destinations uploaded to the tablet on the spot in minutes, and when you finish your vacation, you still have a tablet you can use for other things. You can also sell internet access packages to include with the tablet for the destination mobile system.
Many time I’m listening to a video and my mind wanders as a result of what I hear. I would like to check something that came into my mind, then until the browser downloads the content and renders it, I would also like to jot a short note. I can’t do it today not only because multitasking on smartphones is not very good (or doesn’t exist), but the screen is too small to see it all.
Push the display to an external large screen device like a TV or monitor, a laptop etc. because of the large screen it could be split up and showing multiple apps’ output.
