Smartphone maker BlackBerry has agreed to go private in a $4.7 billion deal led by its biggest shareholder, allowing the on-the-go email pioneer to regroup away from public scrutiny after years of falling fortunes and slumping market share.

BlackBerry, based in Waterloo, Ontario, once dominated the market for secure on-your-hip email. But it introduced consumer-friendly touchscreen smartphones only after it lost the lead to Apple Inc’s iPhone and devices using Google Inc’s Android operating system.

As a leader once shared 53% of the phone market, the BlackBerry prefer to position the products to the high end market, it is really curious why  a market leader give up the most of their consumers but to narrow their revenue steams. In addition, the persistence in the technology is one of the most important factors of the decline of the BlackBerry.

During the last ten years, many other companies like Apple, HTC, Nokia tried their best to develop the user experience of their products such as the camera, the traversing carriage like Passbook in Apple and NFC in Android, the quality of the products and the cost performence. However, the BlackBerry persisted in their full- keyboard design and the system OS which can only provide a few entertainment softwares to their consumers.

For a long time, the RIM model itself a serious and high-end image, which makes their new users confused and the old users feel disappointed because of the conservative strategy of the company and the terrible ecosystem of the platform.

As a result, the BlackBerry missed the chances again and again and, at last, beaten by their opponents.
