Sony has introduced a pint-sized projector that weighs six pounds and four ounces. The VPL-CS7 has a brightness level of 1800 ANSI lumens, an “Off & Go” function (which lets you unplug the unit and carry it away as soon as a presentation is over, without having to wait for the cooling fan to stop), an auto setup that automatically adjusts height and keystone configurations to pre-set levels immediately when powered on, and a password authentication system. The projector will be available in September for about US$1,400.
