Always makes me laugh this type of response -your asleep - your awoken to a knife at your throat or your missus's throat and you go all Hong Kong Fooey and risk a cut to protect a hunk of metal that's insured.
If anyone wanted my S3 - and are willing to break into my house for it for the keys, then they're welcome to it - just leave my wife, kids and me alone upstairs and do it as quietly as possible.
Its insured and not worth traumatising my wife or kids over it. Would I be p'eed off - damn right - is it worth going Ninja for - I dont think so.
I know someone personally who was sat at the dinner table with his missus and some scumbag in a ski mask - walked through his back gate - launched a breeze block through the patio doors glass - whilst he was sat there having his dinner with his wife and demanded the keys to his car.
If theyre willing to do this in broad daylight - its not worth thinking about trying to fight with them.
My keys are hung up within a couple of paces of the back door -out of direct line of sight - but visible if they enter the house. So theyre not rumbling around the house looking for them, with the chance of them coming upstairs where my kids are sleeping.

From someone who knows, the reality is this:
I have been boxing many years (I do some boxing tuition now).........so I can handle myself.
You find yourself woken from a deep sleep by a huge banging/smashing, at 3am in your boxer shorts, to have 4 people (2 inside/2 outside) smash your front door of its hinges, then trying to smash down the bedroom door with crowbars wearing ski masks and stab vests....all within a few seconds of you waking.
Believe me, I did as well as I could just keeping them out of the bedroom (the door frame eventually came off the wall) while my girlfriend was screaming in hysterics on the bed (but not in a sexual way, like it should be lol!).
If you are awake and alert it could be a different proposition.........or if you are armed.
Otherwise, its unlikely you will get a chance to put any well honed fighting skills to use. Even if you did take one of them out, you may well be a marked man from that point on.
I believe that since the courts have toughened up sentences for aggrevated burglary, that a lot of the gangs have now moved on to cannabis farming - as its more profitable, with less risk. Hopefully!
