/shrug. My Evo works. My Palm Pre simply worked (and better at email than BB, IMHO).
WinMo, however, was a disaster. WinMo7 is, IMO, too little, too late.
I don't know if I can agree with the concept that Android phones are inferior to BB phones for email push. I say this because my biggest priority is my EAS work mail account. Moreover, there are hordes of people (at my Fortune 500 company with 50k employees) simply blowing up the IT requisition process for Android phones as soon as Android phones were "officially" available via the IT dept.
As an engineer, all the email and calendar push features work perfectly fine for me. However, I do agree that the better litmus test are the sales and services folks that live and breathe off their mobile devices. And with so many folks in my company in those groups getting Android devices and happy with their decision (with their experiences shared on the intranet forums), I really don't see how Android devices are at a relative disadvantage or are inferior.
