I would love faster checking of email. I have a few accounts and it takes about 5 minutes to check email. My iPad does it in about 20 seconds. Even my N900 was faster.

I am almost dusting of my N900. So many more apps. And not too leggy at 900 MHz.

Faster N9 did make my N9 a lot smoother. Great improvement I recommend. I will probably overclock after everything is working with PR1.3
