Definitely take a look at this brilliant piece at Engadget about the evolution of the Blackberry.

The Blackberry has changed my life in ways I could not have imagined a decade ago. I have owned several of the models in the blackbery evolutionary trail, and I am astounded how far they have come. I can run my entire enterprise from my blackberry wherever I am. I can’t wait to see what my Blackberry in 2019 looks like.
