Projectors are always getting smaller which is a good thing for some users. The business type who is always on the go giving presentations and doesn't want to lug a full-size projector around will like the new 3M MPro150 projector that debuted at CES.
The new projector has 1GB of internal memory for loading presentations and can read microSD cards. A USB port is also built-in that allows the direct transfer of files from computers. The projector can throw an image up to 50-inches and has 15 lumens of brightness.
The device has a built-in MP3 player and a headphone jack and it is a bit over 5-inches long and only weighs 5.6 ounces. It can be preordered now for $395 and will ship in February. 3M also has a very similar MPro120 projector selling for $325.
