Pocket Projector is an apt label for 3M’s MPro150 video projector. It’s not only incredibly small, but it’s completely self-contained, too. All the software you need to display digital photos and videos, PDFs, Word docs, Excel spreadsheets, and even PowerPoint presentations is built right in. You can even store those files in the 1GB of onboard flash memory or on the 2GB MicroSD card that’s included. And it’ll run on either AC or battery power.
