I was thinking of buying the largest selling model of Nokia, the 5510 when I realized that I wanted a phone with inbuilt vibrator to warn me about messages and calls when I am in a meeting. I went in for the 3310 also because the antenna is inside the body, something that wasnt as common 2 years ago as it is now. I have been more than satisfied with the phone in the last 1.5 years. Its quality is good and it handles weak signal rather well. Also it is robustly built and I have dropped it a few times. The battery life is decent enough and I have no reason to complain being an occasional user. I am more than satisfied with this small practical mobile.
