Instead of carrying around a heavy laptop, you can leverage one of the many large displays around you for your computing needs such as displaying a presentation, or checking your calendar, or anything else you can imagine. The displays would be aware of who you are and provide contextually relevant options. For example, if you are in a conference room for a meeting and several of the attendees are running late, the screen could let you know that and maybe pop up the latest news or sports scores for you.
