Haha, Blackberries are NOT dead (unfortunately). You do actually get a lot of business people still using them, over here anyways. I think it's about 30% business men and women with the high end blackberries and 70% college kids (the kind that don't get any GCSEs or at least that have large friend groups where everyone uses a Blackberry for BBM - the kind of people that go around in groups where everyone wears the same thing - ironic considering Blackberry's new atttempt at advertising "if you have Android or iPhone then you're a crowd-folowing sheep whereas if you have a Blackberry you're an individual"!). They're pretty common round here actually.
I personally like Android best but I try not to hate on iPhones, even though they do piss me off sometimes. My opinion is that the Android interface is best suited for me and the iPhone interface best suits iPhones users. It just pisses me off when they say things like 'the Android interface is too complex, the beauty of the iPhone interface is that it's so simple and anyone can use it and the design is most pleasing to the eye, it's like scientifically proven' when, for me the iPhone interface is confusing compared to Android (why does your back button change depending on what I'm looking at? Sometimes it's 'back', sometimes it's 'done', I never know what I'm looking for! On my phone has a dedicated back button - always back, whatever you're doing, like a B button on a gameboy, very reliable) and I think the iPhone interface is awfully ugly. Not everyone is going to like it - that kind of thing is subjective and that's fine, but that's why it's annoying when SOME iPhone users try and tell me that their iPhone is so clearly superior for reasons that can't be proven.
