The LumiTab combines a tablet and a portable projector for the first time8
In contrast to the Galaxy Beam's 15 lumen projector, the one in the LumiaTab should be much stronger with its 35 lumen. The tablet should be capable of projecting an image as big as 100" in diagonal, hopefully without too much degradation in quality. Obviously, the LumiTab will be mainly geared towards the professional crowd out there, but also towards the adventurous geeks who'd like to experiment and play with the portable projector technology.
Besides the projector, the LumiTab will be just a standard mid-range 7" tablet with a lowly resolution of 1024 x 600 pixels, 1.5 GHz dual-core processor, 1GB RAM and 16GB of internal memory. The good news is that it'll come straight with Android 4.2 Jelly Bean. However, exactly when the Promate LumiTab is going to come will have to remain a mystery for now.
