Originally had a newton not really a smart phone but the first real PDA's of the day (by apple) and moved on with a number of bricks since and HP PDA's amoung others. Being a particular Samsung fan although trying my hand with a number of blackberrys on contract from orange more recently, although the physical keyboard and myself had a disagreement but a good phone none the less.
I was sold at the time by the concept of the iPhone as the blackberry was on its last legs and the ipod nano I owned had blown a chip behind the screen causing screen burn, so three devices in one? Bargain
My only reservation is that the screen needs the occasional clean if you’re in the building trade or work in such conditions and that the software was originally behind other phones for certain function but that is no longer the case with 2.0 and 3.0 as well as the SDK
