It's interesting how devices have gone.
Nokia, when they were focused, were making devices smaller, cheaper and with improved battery life. Now we get these giant devices that need re-charging daily and cost >£1000
It's a good point. I think it highlights the fact that these are not really the same kinds of device, so can't be evaluated on the same criteria. If we were still just buying phones nobody would spend that much on something that consumes so much power. The mistake Nokia and the others made was they thought the iPhone was just a phone.
I still remember a Nokia sales rep telling me when iPhone just hitting the shelves that the lack of stylus for input will doom it.
