iPhone, Blackberry, G1 Android, what's your fave and why?

Certainly a hot debate in my office at the moment is one that's not so much about PC, but mobile. The uber androiders, versus the heart my iphoners versus the crackberry brigaders. The other makes aren't even getting a look in I can tell you.

So let's see what people have here and what and why they love their make of smartphone. (Did you know more smartphones were sold in 2009 than normal phones!)

I'll dive in with my G1 HTC T-Mobile Google Android phone - yeah it has a long name, but hey it's an excellent piece of kit and unlike an Apple iPhone my 'apps' are free - I even have the immense BeebPlayer (think BBC iPlayer! and here's a cool bit of info... it was created by a local Beckenhamite!), plus Google maps and SatNav, etc etc

So come on iPhoners and Blackberries what's cool about your handsets?
