The LifeProof is not for everyone, as you can well see with the mixed reviews on the forum. It offers great go-any-where-do-anything protection, that comprehensiveness does come with a cost in both price tag and issues with use (see the numerous reviews around here).
For day to day usageand this case is one you will use everyday, as the waterproofness depends on you not wearing out the o-ring by frequent openingsI like it and forget it is there and get on with my life.
Charging can be a non-issue or a but clumsy/annoying. There's no problem with the Apple OEM sync cable. For anything elseincluding the iPod adaptor cable in my car, for examplethe RadTech (or similar) dock extender is necessary and does introduce some minor annoyance.
All in all, I like it and would recommend it for you, provided that you know what you're getting into and are willing to live with the tradeoffs that come with this level of protection.
