Re: "Remember a few years ago"
But when you get the phone on a contract, as most (i should think) will do, it comes with a lot less cost than a laptop (becuase you're paying for the contract anyway, so ignore the monthly cost from TCO).
By the end of a two year contract. you're going to get more from trading it in than you would have spent on it in cash-up-front terms in the first place. So its not really any sort of comparison with a laptop purcahse that costs you 450 up front, and is only worth 200 2 years later, but is still useful for another couple of years at least.
I have no problem investing say £50 cash at time of purchase to buy a phone that performs its required duties well, never gets a software update, and if kept, only does what it did on day of purchase if i decide to keep it.
Until recently i still had a Nokia 8210 in a drawer as an emergency phone. It never did anything more, or better, than the day i bought it. But it did its job perfectly well, so didnt NEED any updates. Much like my 8 year old laptop that now only gets used to monitor my cctv cameras, its not had a windows update for well over 5 years, but it doesnt care.
