Water proofing would be nice for peace of mind, but to be honest, I've never had a water issue with any phone I've owned so (knock on wood) I don't think that will be an issue.
As far as wireless charging goes, I think that is just stupid and wasteful. It is highly inefficient, wastes energy creates heat, adds bulk and cost to a phone and for what? The minute convenience of not having to plug your phone in? I'll pass. I'm not too lazy to plug a cord in when I want to charge
I've never had a problem with water and my phone either, but that wasn't really my point. The point was that it is a big feature of phones this year, and if they want to charge premium prices, they should be including current premium phone specs.
As far as wireless charging goes, I actually like it. Is it necessary? No. It is just extremely convenient to be able to put my phone on my nightstand at night and not have to fumble around with a cord in the dark. It's also a feature of basically every Android flagship out there, so again, I feel like it should be included at this price point.
