I still don’t understand why companies are placing large amount of memory inside their units…  That is one thing (of the several)  that AAXA did right with the M Ultimate-X by ditching the internal memory and going with the fully expandable SD card option. This is a best practice for a lot of reason but the 2 that immediately come to mind are:  the ability to carry multiple cards/ back ups of your work -and- The ease at which you can transfer data to an SD card Vs. mounting a projector to your computer.

The 3M Pocket Projector MP180 offers an attractive range of features, particularly its brightness and ability to store and display images without a computer or video source.

The current top model in 3M’s pocket projector line-up, it delivers the 32 lumen brightness of the 3M Pocket Projector MP160, teamed with the capability of the 3M Pocket Projector MPro150 to project images from its internal memory or a microSD card.

Like the MP160, it is built using an 800 by 600 LCoS chip paired with a set of red, green, and blue LEDs. However, the MP180 offers the extra bonus of the MPro150’s ability to read files from its internal memory as well as from an SD card. But where the MPro150 has 1GB of internal memory, the MP180 offers 4GB – leaving plenty of space for storing pictures and video clips without the need for a computer or video source.

3M has added WiFi connectivity which allows the user to browse the Internet using the projector’s touch screen interface and there is also Bluetooth data transfer.

According to 3M, the projector offers a screen size of up to 80 inches (203cm) and two hours of battery life.
