LifeProof Iphone case opinions please

I really want to get a Lifeproof Iphone case, because they claim to be 100% waterproof, which is what I really want! But the warranty from what I understand will not replace your phone if the case doesn't work. I need to know if anyone has tried this case and if it works well, because I don't want to spend $80 on a phone case and have it not work, and break my phone.

Installing OSX on a pc via vmware?

I'm looking for a way to install OSX onto my pc so I can run XCode and get into the app developing game. Anyways a mac is way too expensive for me right now, so can I just buy the Mac OS and install it onto my pc? I heard vmware can do something like that from my friend, but the site seems very confusing. So how can install OSX so I can develop iphone apps?

P.S. I don't want to do anything illegal or make a hackintosh or something.
