In my last iteration of smartphone purchase, I bought a latest-at-the-time Iphone 3GS for my wife and the latest-at-the-time Blackberry Bold. Since then I have watched in envy as my wife could get so much done on her phone than I could on my BB. My BB never did much beyond email and BBM ( I love BBM )
In this iteration, I recently placed an order for Nexus 4 and a Iphone 5. maybe if they are still around in 3~4 years from now, sure I could consider going back to BB.
