With the general availability of the Blackberry 10 device starting on Monday of this week, several important questions arise.

Does anybody actually care?  RIM has lost so much momentum to iPhone, Android, and Windows phone.  Can they realistically ever recover? I doubt it.  Still, there are die-hard crackberry addicts who will embrace this new model.  Businesses need to take a bit of a look and see if there is any demand in their user base.  If there is (especially executive demand), then the new management platform may be worth digging into.  RIM wants everybody to use this to manage ALL of their mobile devices.  Whether or not this will actually happen remains to be seen, but BES10 will be needed if you want to support BB10 properly.  Since BES10 is new, it would probably be prudent to wait 6 months or so before deploying it in production.

Gartner has published a fairly concise report on this: http://www.gartner.com/newsroom/id/2374518
