how often you change your mobile and why

i will change twice a year to get a good model.

I feel I had this craze of changing my phone sets before on seeing a new model in the market and feedback from friends, but later I felt its just a waste of money when I dont have a need I should not simply buy it to show off. Its just that I can call and use it for what mobiles are intended for.

As long as i can call and text in my mobile, i don't discard it. But of course, if it really needs replacement because it's so old that no one use that model, then i change it. But as long as it serves its purpose, i don't change it. Well i'll just wait the time when i want a new model for no reason at all then i'll buy a new one. And if one members of the family needs it, i'll gladly give it and buy another one.

i dnt really change it that often un less it breaks or something like that..but i dnt see the need to just change it 4 the heck of it
