It's not something new and we've seen plenty of accessories or phones that have a built-in projector. One of the glaring issues with most of them is usually the lack of battery time with the device. Nokia has a concept in mind dubbed as the “Nokia Pulse” that will allow users to use the accessory and control its functions through a cell phone
. The obvious features are the ability to project an image or video on any surface - and also be able to adjust it via controls on your phone. So all you do is plop the device on a surface and use your mobile phone to have your projection moved. It'll also have a NXT speaker with Dolby technology. While not ground breaking, let's just hope that the battery life will exceed the expectations of users.
