HP Combo Notebook/Projector Speculation - More Questions Than Answers

HP to launch mini-projector-integrated notebook

While this sounds like a desirable combo, here’s a couple of things I wonder about such a hybrid notebook-projector:

– How hot does it get when the projector is running and how does this affect the notebook’s other electronic components?
– How much of a “throw” does the projector have and how large of an image can it project?
– How easy (or difficult) will it be to find a replacement bulb?
– Will replacement bulbs cost an arm and a leg?
– How big (heavy) will these combos be?
– How much will they cost?
