which of this phone will you go for? E6, E5, x peria arc or window mobile? E6 and E5 are both great phones by nokia company but they are now diverting their technology to window thereby neglecting symbian. There is no updates again for symbian phone and in 3 to 4 years time, symbian software will no longer exist.
Xperia arc is a great phone made by sony ericsson but the only complain that the users are making is that the battery life of this mobile is poor.
E6 has 8mp camera mode with 8mg internal memory, 256RAM. Although, the brand new of this phone is scarce and the price of hand to hand is valued around 30k which can be used to get brand new of nokia E5 with 2.5k in hand. However, one need to add 4k to purchase d brand new of X peria arc. So which one will you go for if it happens that you need to choose one out of this mobile phone?
