I should get me one of these -- that way my nieces and nephews will finally keep their damn dirty hands off my phone!
But in all seriousness -- personally I've found flip cases to be kinda clunky
The front cover just makes it way too awkward when taking pictures -- or sometimes it will actually overlay the photo lens.
Maybe I'm just clumsy, but that's my experience
Then again, I take a lot of pictures with my phone -- so for most people its probably not an issue.
