Reading above regarding the battery life of the s3 not bieng as good as iPhone 4...
I've had my s3 a while now, my battery wallops the iPhone 4 it replaces.
The s3 is better than the iPhone 4 for sure.
As for customer service, if I have a problem it goes back to orange, they supplied it, they honour the guarantee. If I break it, I have a new one within 24 hrs.
If Apple bring out a phone that's better at my renewal time then I'll switch back to Apple for a while. It does make me laugh at the brand whores that put Apple on such a high pedestal and rubbish everything else, to the point about Samsung copying their stuff (bullshit, may as well say that their pc o/s was a tweaked windows copy then).
Apple make extremely high quality, high performance tech. I can't fault build quality, but they certainly aren't the be all and end all.
My 2p
*edit* I just looked at the specs, and once again the 'new' phone just isn't new enough to go "wow, I have to have that". Apple need to up their game.
