It is good to hear these valid points, and although I had wished for the same when water reflections were added, I agree with this thread that it's benefit would be almost entirely eye candy, and therefore at the bottom of the to do list for HTC.
My question back then, was to ponder if the same coding to make the water reflective would be instrumental in making mirrors reflective also? Being ignorant about code, I was just wondering if they had some possible tricks used with the water (code already written) that could be useful with mirrors?
