There is now a coating technology that can make electronic devices waterproof without a housing. Don't recall the name of the process but micro particles are deposited on all internal and external surfaces. Similar to the concept of putting meat or fish in a smoker. Pressure is applied during the process and the device can be immersed in water. Sorry I can't recall the source of the info, I spend too much time surfing but it might have been AP news or new york times technology section. So if my phone ran a good dive computer app, had a digital compass, could follow gps underwater, had automatic fish id, had side scan sonar, was a metal detector, blood gas analyzer, O2 and CO detector, allowed me to make underwater calls and send photos, played my favorite music at the right times, translated languages, 1200 watt daylight spectrum dive light/strobe, shot hd as least as good as my sony hdr not the crap from the gopro, preferable as good as a RED, forget 1080p I want 4000p, Air intergrated so no hoses and transmitter to an augmented reality Google goggles and most importantly allowed me to pour unlimited beer from it after the dive,yes then I would very much like to dive with a smartphone.
