To be fair I generally use a lot of the stuff I buy.
I deffinetly have got my moneys worth out of my Iphone, 40" TV and top end Pc/Xbox
I watch TV almost every evening for atleast 30 mins, same with the computer, I use the iphone all the time for browsing the web and getting information and obviously texting/phoning people. With my N95 or XDA I didn;'t bother because it was too hard to use and not included in the package and cost a bomb.
What is different is people aquirring new items they don't need to show off.
Recently it is people buying Iphones/Blackberries just because they are cool or Landrovers to drive the kids to school.
They are status symbols as much as anything in some ways. but I don't call spending half my wage or getting finance on a car cool bit sad tbh. If you can afford it and need it then fair enough.
I got a almost brand new car, this was probably the biggest mistake but it was a gift and had to be new. If it was my money I would have purchased something older.
However now I have all these things I don't iintend to spend any more on them until I need to. Yes I could buy a 46" TV but I think I will atleast wait for 50"+
