Choosing the best Mobile

I had been searching on the internet from the past 3 days for a very good mobile. I had planned for an Apple iPhone but dropped that because of some reasons. I was looking to buy a Nokia N95 or a HTC touch diamond. I found that HTC Touch Diamond was very good with lots and lots of features. But I had got more interest for Nokia Mobiles as I was using them from the past 10 years. So I was confused very much. So I decided to look at all the factors present in both the mobiles and choose the best one.
