Fair point. I mean £1,500 for a bloody phone is absurd; aside from a Blackbird and a petrol BMW, that sort of money could buy a decent laptop.
However, everyone has their 'thing' and mine is my toys. I buy a new phone whenever I feel like because I don't piss money up the wall on things that other people consider a priority. By that, I mean we both work full time, we don't have kids and I don't drink (apart from the four weeks a year we're on holiday), I don't smoke, I don't gamble, I don't do drugs and I don't do scruffy women. Once my financial commitments are taken care of, my disposable income goes on food, fuel, sports supplements (protein, creatine, aminos, etc.) and my toys.
I don't pay for phone usage as such because I have my business sim card in it. My employers provide a phone and we can use it for whatever whenever providing we don't take the piss. I just choose my own handset and pay for it myself because I don't like the Android shite that the company prefers.
