The Great Debate: iPhone vs Droid vs Blackberry

So, I am officially at the virtual crossroad of phone purchase.  Not only is it phone purchase, but it’s full-retail or pre-owned phone purchase; making the dollar investment higher, thus the commitment is a bit more important.  I’ve had an iPhone since 2007, purchased my first Blackberry 2010, and have never had a Droid, which actually has me intrigued at the prospect of trying something new.  I’ve given this a considerable amount of thought, which I’ll break down in detail soon.
