Presentations. Having an tablet is great for presentations. I can carry it with me or do a fireside chat holding it and running things exactly as I did when creating it. Using AirPlay is easy because it is in most places I go and if not I do carry the dongle for HDMI (which I need on most of the laptops I use anyway). The ability to drop the keyboard and the overall device size/weight make this one a great scenario. I love having my notes handy as well in a “socially acceptable” form.

This is definitely one of the prime use cases and where tablets, more especially the iPad over Android models, shines compared to laptops.
