Looks and Size:
Nokia C7 in India has a pebble-esque look with nicely curved edges and a large screen. The surface is a combination of metal and plastic and gives you a very firm hold. The shinny looks and super glossy fascia is bound to impress one and all. The phone weighs merely 130g. Nokia E6 in India on the other hand has more of a sturdy look but still elegant in its way. It is an extension to their business smart phones so the look is not really aimed to be attractive; rather it’s more on the business phone side. The phone hold nice and firm in hand and raised keys makes typing a pleasure. The phone weighs only 133g. Both the phones have got the looks and it really your preference whether you choose the business style or the one that is funkier.
Nokia C7 features AMOLED capacitive touch screen with 16M color. It has a giant 3.5 inch screen with a resolution of 360*480.Nokia E6 on the other hand has TFT capacitive touchscreen with 16M color support, 480*640 resolution and screen size of 2.46 inch, something that you would expect in a design with full QWERTY keyboard but the punchy and vibrant colors are class apart especially when fascia is turned from reflective mirror to a bright AMOLED display which gives C7 a slight advantage on the display front. Due to the presence of Touch and Type feature, my vote goes to Nokia E6 in this case.
Both the smart phones feature 8MP camera with resolution of 3264*2448 and autofocus and dual LED. We are talking of Nokia devices here so the camera performance is more likely to be the same. Both phones are able to record HD 720p video at 25fps and also feature a 0.3MP front camera.
Processor and OS:
C7 features a 680 MHz ARM 11 processor running on the symbian 3 OS. The processing power of E6 is slightly lesser with 600Mhz processor but features a 2D/3D graphics HW accelerator and the latest Nokia anna OS which gives it a slight advantage over C7.
The storage capacity of both the phone is same with internal storage capacity of 8GB, 256MB of RAM, 512MB ROM and microsd card support up to 32GB.
E6 may be aimed to be a business smart phone but the most of the features that it offers are also available in C7 like the quick office document viewer, adobe reader, voice command and predictive text input. Both phones also provide excellent entertainment and connectivity features. So as it turns out the looks of these Nokia devices is what is going to be a deciding factor when you are looking to choice between the two.
