Nokia E7-00

The Nokia E7-00, also known as Nokia E7, is a business-oriented QWERTY smartphone by Nokia from the Nokia Eseries. It was announced at Nokia World in September 2010 together with the Nokia C6-01 and Nokia C7 and started shipping in February 2011. It is the second phone after the Nokia N8 to be running the Symbian^3 operating system.
When compared with the Nokia N8, it has fixed mass storage of 16GB without a memory card slot, no FM transmitter and a less advanced camera, with Extended Depth of Field, instead of autofocus as in the N8 and the E90. Like the Nokia N8, it comes with an HDMI-out connector and a non-user-replaceable battery that is smaller than the E90's.
It has the same keyboard spring mechanism as the Nokia N97 mini, but has like the N8 an anodized aluminium casing. All this is different from the bulkier and heavier E90.
Compared to the Nokia N97 mini and E90, the E7-00 has a multitouch capacitive touchscreen. Unlike the N8, N97 mini, and the E90, the E7-00 has an Active-matrix OLED (AMOLED) ClearBlack technology with a slightly lower resolution than the E90.
Vlasta Berka, general manager of Nokia Singapore, Malaysia and Brunei, talked about the trend of users who are using their smartphones for business.
Criticism.
The Parliament of Finland bought 200 E7s in spring 2011; by late April 2012, over 50 of these phones had been serviced under warranty. Most of them were fixed by OS update 
The E7's battery is not user-removable, although unofficial online tutorials on how to replace the battery exist.
Being one of Nokia's first phone designs without a dedicated connector for charging, the USB connector in the E7 is also used for charging, and is a common point of failure.
