Apple's New iPhone Applications No Threat to RIM's BlackBerry

RIM's infrastructure costs alone, when compared to setting up a compatible MS Exchange/Smartphone (and now iPhone) setups, are too high. That will stall any new investment.

Existing setups will take a long, long time to show ROI, and then by that time you can start a process that puts RIM and it's cacaphony of BES-systems-galore as well as more licensing than you can shake a a stick at; all behind you.

As unique as RIM's BES setup is, it can't beat the simplicy of the MS Exchange push process, as well as the wide compatibility of devices.
