My friend and I brought this model in August 2007. We both share our disappointment. The phone keeps on hanging most of time. The less said about the battery life, the better. In fact my initial phones were only Nokia models - 3315, 1100, 6610i, 2310 and finally N72. Based on my previous experience and comfort of the Nokia brand, I trusted and bought N72.
After getting to this model, I resolved to never again for Nokia brands(and I am not one to change loyalties frequently). Subsequently, I have gone for Sony and LG mobiles and they are giving good service and value for money.
Rather than rushing to the market with a new model, I hope not just Nokia but all other brands test it fully before bringing it to the market.
