There's a picture of it in a glass of water and yet no comment about that. Have they finally made use of the hydrophobic coating stuff that has been more and more in the news.

I saw a piece on Click I think where someone had developed a process to waterproof basically anything. Essentially you put whatever you wanted to waterproof in something that looks like a small oven. That oven was filled with an ionised gas at high(ish) temperature, which caused a nanoscopically thin layer of gas molecules to adhere to the surface of whatever it was. That made the thing waterproof, at least for a period (long exposure in water would dissolve away the molecular coating) while still allowing things like USB plugs and even touchscreens to still work. Quite impressive.
