In my experience, the battery life in most phones is fairly disappointing at the moment. I imagine that this would be a major hindrance to the usefulness of a projector. The increase in efficiency that this lens provides is great news but actual power consumption would be a more useful figure than a percent improvement. How much power will a small projector consume compared to a typical LCD screen? Personally I would be much more excited to see LCDs with reflective modes rather than projectors. These would alleviate battery issues, solve the problem of screen clarity in direct light, and also ease eye strain. I'm keeping my fingers crossed :-).
