It takes time to be really up to date with everything.
You have to rememeber it took years for Samsung to be where they are.
They were struggling in the past for a long time, with wrong hardware and software decisions.
HTC was on top once but is not right now...
Most manufacturers update only some of their phones, not all.
I agree Sony has to be faster.
But they improved massively in the recent years, starting from X10.
