Which means you haven't been getting & enjoying photos of trips in the interim, which you can't go back and take since that time is past.
If the current state of technology isn't quite what you're after, do the best you can with what's available, and in 3 or 4 years buy another that's better.
Or forfeit the photos you could take & enjoy in the interim waiting for an excellent case-less submersible point & shoot with excellent photo quality that's not real expensive.
Could be quite a wait, if history has taught us rightly. I've been watching this market off & on, too, with similar frustrations.
Following up with Peter said, think about a compact Canon in an underwater case. Could still be pretty small, and a case rated for scuba diving ought to be good protection for a snorkeler, plus it might take better photos on land.
