Research In Motion hosted BlackBerry World 2011 this past week, in Florida. As an avid BlackBerry user, while I didn’t attend, I was interested in the following:

1. The new BlackBerry Bold smartphones, that combine a keyboard and a touch-sensitive display. I remain a firm believer in the power of a real keyboard on a smartphone, and I’m interested to see how this goes with the combination of the new display.

2. A new video chat application for the PlayBook. The press release talks about video calling over Wi-Fi, but I’m assuming it works over cellular / 3G too.

3. New device and security management capabilities for BlackBerry smartphones and the PlayBook tablet, with forthcoming support for Android and iOS-based devices too. That’s a good play – kudos to RIM.

4. A new way of separating work and life content on a single device. It may do it, and if it did it would be excellent, but there is no mention of separate recording of data traffic per “side” – one recording for work stuff, and one recording for life stuff. That would help deal with the biggest challenge from mixed purpose devices, but would of course require an equal up-leveling from the carriers.
