Microsoft Outlook = Blackberry

Outlook is the smartphone keyboard. There's absolutely no reason for it. 

4 years ago I would often rail against the Blackberry during public speaking engagements. People wanted a better experience on their mobile device, "we want to be able to xyz" and I would tell them "no problem, just get rid of the Blackberry" ... nobody needed to say anything, the looks said it all, "this kid is crazy." 

No way Blackberries were going anywhere people would say, "yeah but businesses" ... they had all kinds of reasons but the argument was never "the Blackberry is better". Everyone agreed the Blackberry offered a subpar experience, corporate employees carried around two smartphones. The only reason anyone used a Blackberry was because they "had to", no one wanted to.

The trend of technology hitting its stride with consumers first and then working its way into corporate america is known as consumerization.  The iPhone and the iPad offer the two best examples, but they were just the tip of the spear. 

Corporate employees are also taking other matters into their own hands when it comes to applications. Personal Gmail and Drive accounts, Dropbox, Box, Evernote and thousands of other "consumer" apps. 

IT executives and small business owners often tell me "we can't get rid of Outlook" and the reasons sound pretty familiar. I ask them if they use Outlook for their personal email, "no way, why would I do that?"

...you don't use it at home because it's slow to start, slow to close, hard to setup, hard to support, not mobile, not really available on your spouses Mac, etc. etc. etc. 

No one uses Outlook because they want to.  There are exponentially better options.
