Now thats just what i currently hace on my phone, only upgraded to 3.0 the other day so still bulding up my apps. Now you can clearly see that is far more than double what your phone can do, withought even looking at the 100000's of other apps, so how can you say it is not worth twice the price?
So realy, it's your phone that is over priced
