Being able to deliver a presentation direct from your tablet is handy: no messing around with loading files from USB or grappling with laptop changeovers. Just remember: put your device in flight mode first so you don't get bombarded with notifications.

I've attended to at least two events in the past month where the tablet-wielding presenter has been interrupted by a notification from Twitter. In one case, it actually showed up on screen; in another, the speaker was sufficiently distracted to lose his train of thought.
Your presentation viewer may offer the facility to switch off notifications, but not all do. Going into flight mode ensures no external messages will pop up at an unexpected time. Have another tactic you favour to avoid tablet presentation dramas? Share it in the comments.
