Having 'higher' stats means nothing if the software/os is not optimised to use it. Having a high megapixel camera also does not mean quality pictures.
Looking at that table, they are all very similar specced and priced.
And the fixation people have on flash makes me laugh. Try using flash on your android devices, it's the fact they are a touch interface that it fails. HTML5 is well on its way to putting flash in the grave. And for 90% of the flash sites out there, there is an app for that
End of the day it is going to come down to applications and ease of use. Apple has the upperhand here as the iOS system is the 'norm'. Android is well on it's way and has some cool features the Apple units don't have, but having to hack your brand new Nexus S phone to try to get some useable battery life out of it will turn people away.
