Mine has always been a Motorola. My current model is the Z3 flip lid.
My needs are very simple so the infamous Blackberry wouldn't suit me. Too many gadgets and I prefer to answer emails on my computer rather than having my mail following me around. So the Motorola, provided by O2, is excellent. It can also play music but I don't use that facility too much as I already have an Ipod. But it takes beautiful photos (as you can see from the collection here when I went to Downing Street during the G20 summit at the time of the special dinner for the world leaders). I was crestfallen when I realised on the train that my camera was not in my bag but my phone came to the rescue. The reception is also excellent no matter where in the country I am, it is easy to navigate and very user friendly.
Each year I update my phone to the latest one but I never change the model. I guess Motorola and I are a great team! :o)
But what about you? Which flashy phone do you have and why?
