I think what he's saying though is that very few companies have actually abandoned or switched over from BB. Almost everyone I know in several industries still use Blackberries. There's no talk yet of a massive changeover.
I know what he's saying, and I'm flat out disagreeing with it. I work in Nashville, which is the epicenter of the healthcare technology industry. There are 5 shops in the healthcare field alone that employee 20K+ employees. I've worked for two of them, and have contacts at the rest. Of those 5, 3 have already moved off of BB's platform (2 android, 1 iPhone) and another is going to do so when they finish their Exchange upgrade from 2007 to 2010. I no longer work in healthcare IT,but my company ( a government agency) has abandoned Blackberry over the last year, as well, in favor of Android devices. We have one legacy BES that is still active, for employees with personal devices linked, but we've notified them that the server will be retired on September 1, and if they wish to continue receiving e-mail, they need to switch to an ActiveSync-compatible device.
It's a no brainer from a cost perspective. Either way, you have to pay for the Microsoft Exchange CAL(client access license), but with Blackberry, you ALSO have to pay for an expensive BlackBerry Enterprise CAL, essentially doubling your cost. That's not even accounting for the cost associated with running the BES (hardware, cooling, power, OS license, etc). Conversely, ActiveSync is native to Exchange--it requires no additional hardware or licensing.
From a device standpoint, we can get our Android devices (HTC EVO Shifts) at about 75 percent of the cost of the Blackberry Curve, our previous corporate device, and our users like the experience and features of the Android better. Again..it's a no brainer.
Obviously this is all somewhat speculative, but I consider myself pretty connected with the IT world, and as I've mentioned, I have a lot of contacts. Unless Nashville is some sort of vacuum, the movement is, without a doubt, getting away from Blackberry. Being conscious of all of the factors I just mentioned, I can't think that it's any different anywhere else. To reiterate...a company has to pay considerably more and dedicate more overhead to a product that doesn't offer anything to justify the added cost.
