Also EAS forces you to download the whole attachment as well the email which causes a longer pull. BES pushes 4k chuncks which provide a quicker delivery. Not a huge factor with 3G but all you iPhone users must see how EAS just sucks down your battery - why? EAS is chatty as it is constantly asking Exchange for new mail. Sure you can opt to just poll ever X mins but what good is that? It's 2009 and push / OTA is where it's at.
That's just performance. To get the real value of BES and understand why it's the standard for almost every major company:
Ability to control / lock every option on the BB if you choose
Device level encryption as well MicroSD encryption
SMS/TXT/Phone call logging
MDS gateway - secure VPN access via BES to your network
Full reporting / asset management of your mobile workforce.
iPhone has NONE of that control and Windows Mobile requires you to buy System Center Mobile Device Manager 2008 (Seperate server, extra CAL = $$$) So while this appears a great / similar experiece to the end user. It is anything but when you have to manage and control all these devices.
very nice pieces of information here, thanks!
