3M MP180 Pocket Projector

Pocket projectors are still a niche product, but are becoming more common. Manufacturers are beginning to integrate them into other devices such as cameras and camcorders, but they're little more than gimmicks. 3M's latest model - the chunky MP180 - hopes to appeal to the travelling presenter, and is the most feature-packed pico projector we've seen.

The most obvious extra is the colour LCD screen on the top of the unit. This 2.4in display makes a lot of sense as you can browse files stored in the 4GB of built-in memory as well as the contents of an inserted microSD card without needing to actually project an image.

The resistive touchscreen display requires a firm prod.

As it's a touchscreen, control is intuitive, but it wasn't quite as responsive as we've come to expect from modern capacitive screens - this is a resistive display which requires a firm prod. Occasionally the MP180's processing power appeared to be the weak link, as we were left waiting for menus to appear for several seconds after trying to exit an application.

The strangest built-in application is the web browser. This connects to the internet using the integrated Wi-Fi radio - websites are then displayed straight onto the nearest flat surface. Unfortunately, the browser looks like an ancient version of Internet Explorer. Entering a web address or Google search term is fiddly due to the tiny keyboard which appears on the 2.4in LCD screen. Trickier still is controlling the mouse pointer with the touchscreen - we found it almost impossible to be accurate. Worse still, you can't tap the screen anywhere to click; you have to prod a specific area at the bottom, requiring you to take your eyes off the projected screen to find it.
