Got a chance to test out the new Samsung Galaxy Beam this AM. Not only is it a phone, but it also has a built-in 15 lumens projector. This device is slick. Not to mention that it is totally in-line with my penchant for mobile-only.
Samsung also includes a slide display app that would allow you to use the device to show your PowerPoint slides in a meeting. The app allows for on screen annotations as well.
