"We've already seen a few patent applications that suggest Apple is at least mulling over the idea of using projectors for one purpose or another, and another newly published one has now offered a bit more fodder for speculation. Described as a \"display system having coherent and incoherent light sources,\" the patent application suggests that the projector would be laser-based, and be both cheaper and more power efficient than conventional light projectors, while also overcoming the so-called \"speckle\" problem sometimes seen with laser projectors. What's perhaps most interesting, however, is that the patent application also suggests the projector could be integrated into other devices -- in fact, one of the claims specifically mentions a laptop with an integrated projector, as artfully illustrated above."^^<http://www.w3.org/2001/XMLSchema#string>
