This comparison of OS's is interesting.. I for 1 have been using nokia for the past 3yrs and i can say its a good OS but ever since Android hit the market competition has become stiff.. Its down to the general appeal that you get from using the OS and its user frendlyness.. Thats why am getting my self an android powered phone to experience this new OS (but alonside my all time fav OS - Symbian)
