ITreviewed posted a review on the Dell M109S Micro Projector

If you are looking for a projector you can carry with minimal effort so you can give presentations just about anywhere, Dell's M109S fits the bill. It's so small that it is guaranteed to impress your clients. The downside is that colours are washed-out compared to regular projectors and it is not very bright. There is no remote control, the touch-sensitive control panel is a pain, and an operating noise level of 32dB/35dB (Normal/Bright mode) is louder than I expected. Another annoyance is that the cable with the VGA connector is only about 2.5 feet long, which resulted in my laptop tugging the projector out of position. Still, it handles PowerPoint presentations with aplomb. If it makes you feel any better, you'd be investing in one of the most eco-conscious display technologies out there. But when there are really great performers are out there for the same price or less, you really are paying a price premium for the size.
