A few days ago I ran across an interesting device in a local electronic store. Finally it is time when such device arrived at our lives with satisfying performance for an affordable price. I found that buying it as a new PDA/phone accessory would be worth considering. It is an ultra-mobile (size: 2.0×0.9×4.5″, weight: 5.6 oz, battery life: 40-60 minutes) handheld projector which uses LED technology to project an image up to 50 inches in diagonal. It might potentially solve the burden of a small phone screen.
Although, the video shows some potential applications, it is still not clear what the killer app will be, how the mobile phone users will accept mobile projectors (regarding privacy), and how the projectors will enhance user experience and multi-user interaction.
