One of my friends has always told me about android smart phones because he doesn't rate blackberry as phone but I have always argued that blackberry is the best not until I got my sony xperia p I now feel like I have just been released from bondage of blackberribitis. Though I still have my bb just for pinging and nothing more with the bbm coming to android os and ios is going to a great experience to the end. Blackberry is dead.
Note: this is just my opinion whatever phone one chooses to use is ones decision as long as it serves the purpose it is being used for.
