7. Applications: Another huge consideration is the number of 3rd party applications that can be downloaded. In this respect Windows Mobile clearly dominates; popular software site Mobihand lists well over 10,000 apps for Windows Mobile, with less than 4000 applications for Blackberry Units, thus showing the reach WindowsMobile has with developers. A Quick search of "Windows Mobile Freeware" brough back over 6 million Google hits vs. "Blackberry Freeware" on Google which revealed 290,000 responses.
8. Fees: Email is free to access, outside of data charges when using Windows Mobile, while a BES server connect fee is charged for use with the Blackberry Client. Not to mention if Blackberry servers experience an issue network administrators are at the mercy of Research In Motion to fix the server, in fact technical glitches in the past have led to Blackberry users around the world losing access to their email while the problems were being solved. Whereas Microsoft Exchange sends email information directly to the users device meaning more control for administrators.
9. BES: Finally, BES servers which control Blackberry Email are considered to be among the best in the industry for security, meaning better controlled access to your email files, although Windows Mobile offers device storage wiping if you lose your device or its stolen, so this is a hard pitch to decide on. I'd personally call the email functions that Blackberry use to stand on a draw.
These are some of the big differences between the devices, as you can see when it comes down to Windows Mobile vs Blackberry, Microsoft dominates the Blackberry OS on almost every front. While Blackberry does offer excellent email capabilities and a generally reliable server backbone, Research In Motion still has a long way to go in terms of creating better all around devices. The iPhone has recently shown that business users expect their devices to work around their needs and Blackberry stilll lags behind Windows Mobile in delivering a full suite of applications both for work and pleasure that work together in unison to offer a full user experience.
