DiveNav's been selling the Android/iOS app for some time now, so I'm not sure why this is news...
Anyway, AFAIK preemption strategies in linux kernel are configurable at compile time and RT-preempt patch allows single-digit-millisecond latencies (we don't know how google's configured any given android kernel, of course, and I've no idea what's inside iProducts at all). But anyway I think the response time required here is in single-digit seconds so I wouldn't be too worried about that. I'd be far more interested in where the buttons are -- did they figure out how to make the touchscreen work underwater in gloves?
