It has a large 4" AMOLED display with ClearBlack technology, 8MP camera with LED flash, and 16GB of internal memory, in addition to the HDMI-out port, and USB-on-the-go functions. Typing those emails while in motion should be a breeze on the excellent slide-out keyboard, and the thickness is that of the Nokia N8, despite the keyboard. Of course, the Nokia E7 doesn't have the huge camera sensor of the N8.
It should be shipping with the newest firmware version 13.016, the so-called PR 1.1, which has improved email capabilities and the option to edit MS Office documents without having to pay and upgrade Quickoffice. A major firmware update later on is PR 2.0, which will feature the improved browser, portrait QWERTY and keyboards that can be overlayed on a page.
There is a plethora of corporate communication functions on the Nokia E7, which remind you that this one is predominantly the business type. Your corporate IT department can manage the phone remotely, it can be locked and wiped from afar, as well as displayed on a map if stolen. The Nokia Mobile VPN client comes preinstalled for secure communication with your company's intranet, and so does Mail for Exchange.
