Why Smartphones can be Dumbphones

At first I quite agree with the above statement. It is just too expensive to surf net, check emails, twittering and FBing by using smartphone without a data plan. It cost a bomb. Most of the time we use the smartphone to make phone calls and book our diary. If the telco company able to offer reasonable data plan price, I think it really change our lifestyle. Smartphone is no more dumbphone but SUPERPHONE !!!!!!
