The Communicator was a great beast, and better than the Ericsson R380 I had the pleasure of using for a while. The R380 had a semi flip front and could be viewed in portrait and landscape - even had touch screen keypad entry with a plastic pen - but it was monochrome and so chunky that you'd struggle to stuff it into the bulkiest of pockets. But that was over 15 years ago.
I agree with you on upgrade, too. In fact, I'd go further. I think most model updates bring very little of true progress, but every now and again there is a giant leap forward. Nokia 3310, 8880, 9000, Ericsson T68, iPhone, iPhone 4... Easily seen with 20/20 hindsight, but to recognise the leap forward in the moment. Hang on, this is a whole other new thread, isn't it?
