Smaller, better, faster, cheaper. Over the past 25 years, this simultaneous progression has become the accepted standard in things computer. As new generations of projectors have come onstream in recent years, the same happy pattern is being seen again.

	SMALLER	They pack more performance power into an eversmaller package, take up less room in the presentation setting, and are increasingly less likely to dislocate a shoulder if you buy your own and have to carry it from one venue to the next.
	BETTER	Lumen levels and screen resolution are up, difficulty to master is down, compatibility is less and less of an issue, and reliability is several orders of magnitude greater compared to earlier forms of the technology.
	FASTER	Newer forms of technology use increasingly faster and more powerful computer chips and other components to provide greatly improved performance, even when incorporating streaming video and live video feeds. Screen refresh rates that used to be measured in seconds are now calculated in milliseconds.
	CHEAPER	At the same time quality has improved, prices have spiraled downward into a range even part-time presenters can afford to explore. That is having ripple effects on rental prices and the frequency with which meeting sites and their suppliers can upgrade their AV equipment.

As a presenter, chances are the choice of a projection system won't be a frequent issue. Either you (or your organization) will decide on and purchase a projector, and over time you'll become familiar with its specific workings. Or you'll learn to mate up with whatever technology is already in place in the meeting venues in which you present - perhaps in the process developing a concise list of standard expectations you can share in advance with a meeting site contact to make sure you are provided with a proper system for both you and your audience.
