As is the case with most office products, projectors have a few important features which are crucial to understand before making the right purchase. While deciding what weight you want your projector to have will help you decide on the right display type, it's still important to understand concepts like resolution, brightness, and lens specifications, whether the projector is headed for the auditorium or overhead compartment.

Weight
The first feature that you should decide upon is weight. If you're not sure of an ideal weight, you may want to ask yourself if weight is even an issue for the projector. If your projector is going to be mounted in a board room or carted from office to office, how much the projector weighs isn't going to be a key consideration.

On the other hand, if you plan to present on-site sales pitches or conference material, weight will be critical to your future happiness. While a pound or two may not sound significant, consider lugging a projector from the office to a taxi onto an airplane, back in the taxi and then over to the conference center. And don't forget you're already responsible for your laptop, your notes, and any other extraneous materials.

The lightest models on the market are now tipping the scales just below five pounds. While ultralights have gotten lighter and lighter in the past three years, weights appear to have stabilized somewhat as projectors are about as light as they're going to get for the time being. Don't forget that the unit's weight doesn't equal what you'll carry through the airport. Be sure to ask about the total weight of the package, including the carrying case and any other peripherals that come with the unit.
