Why did Obama like using a BlackBerry?

Obama was known to love his Blackberry. In fact, he was so attached to it, he got to keep it after his presidency ended. But...why did he find it so wonderful? For one thing, Obama was the first president who was in office during the high tech infiltration. He used a Blackberry because they were one of the first available and were thought to be very secure. It is likely that he just got used to using his beloved device and since people aren't usually fond of change, it's possible he didn't want to learn a whole new phone system.

Furthermore, even though his emails will be monitored due to the fact it is the same one he had when in office and he worked it out so that he could take it with him, there still are features Blackberry offers that most other phones doen't. The reasons are many that Obama loves his Blackberry and a certain amount of the population who have it swear by it too.
