IE9 is not available on OS X and most Linux distros.
Not the same :)
The reason that there's so much focus on web standards is because Microsoft used their browser to force platform lock-in.
I don't see going webkit only as being a problem: Chrome is available on the three major PC operating systems (Windows, MacOS, Linux), it's free and it's not owned by a PC OS vendor.
Now if it was Safari-only or IE-only, then that would be a problem.
So yeah, while you're technically correct by your wording alone, I'd argue you're wrong in spirit.
