Here we would like to mention Nokia E66 – an analog of Nokia E71 smartphone, deprived of a full-size QWERTY-keyboard and executed in the slider form factor. The corporate design of Eseries line further emphasizes the business status of the model. Compared with its predecessor, Nokia E65, the model lost the strange frivolity in design (for example, the red color version of the case), acquiring solid form and content. Retaining the verified design, excellent ergonomics, decent case materials and build quality (causing criticism in a number of other models of the company), the smartphone has received numerous innovations – such as support for Wi-Fi (in corporate interests it supports all security standards), GPS, 3,2 — megapixel camera with autofocus. The Symbian OS S60 3rd Edition software platform allows you to calculate the abundance of third-party software, including business functions.
