This is rather amusing. Got it from this page.
iPhone users are actually pretty regular people who just think they are oh so cool. Blackberry users think iPhone users are childish idiots with all the useless apps and Android users think iPhone users are brainwashed by Steve Jobs.
The Android user is a little boring but sees himself as being smarter than most, iPhone users think the Android user is an uncool dork and Blackberry users who have no clue about Android believes the Android user can only make a living by delivering pizzas.
The Blackberry user is typically a white-collar sales rep, who thinks he is the big shot business man, iPhone users sees the Blackberry user as as an aged sales person and soooo yesterday. The Android users can’t even bother looking in the direction of the Blackberry user and his dinosaur phone.
