You get a notification from your calendar that you have a meeting RIGHT NOW, you completely forgot about it, go to your email app to find the meeting link -scroll scroll scroll, search search search- WAIT it's not there? Back to the calendar app to see if the link was on the invite. Oh here it is, click on the link which takes you to another app to have your meeting. How much time did that take you? How many apps did you have to open?
