Maximum PC: If mobility is the name of the game, Acer's K335 portable projector won't bog you down. On the contrary, Acer says its newest projector weighs a mere 2.8 pounds -- that's Ultrabook territory -- and measures 9.1 inches by 6.5 inches by 1.8 inches, small enough to fit easily in a briefcase or backback. That being the case, Acer is pitching the K335 LED projector as being suitable for both home entertainment and business presentations.
