Compared to most of the Smartphones which are Android based, the Nokia C6 Touchscreen Mobile has a very user friendly and intuitive interface, allowing you to learn to use it without much referring to the fairly comprehensive user manual supplied. Battery lasts for a long time and if you use it sparingly, it can be several days before you need to recharge it.  The Nokia PC suite (which can be downloaded from the Nokia website) allows easy transfer and saving of data from the Nokia C6 to your desktop or laptop.

However, compared to Android based phones like the LG  Optimus One and Dell XCD 28, the speaker volume is lower  when you use the speaker mode.

Initially in December , the price of this smartphone model was Rs 10000+ ($250),  but in the last month, the phone prices have reduced drastically.

Less than a year ago, a Seagate 1 TB drive cost more than $100 and was bulky with a separate power supply.

Today, a 1 TB Toshiba Canvio 2.5″ drive is available at a lower cost and is very light and compact. It does not need a separate power supply.
