Microsoft on Monday, Apr 13 launched Kin One and Kin Two aimed at the younger consumers in the age bracket of 15 to 25 years. While both the phones have common features such as touchscreen, slide-out keyboard and camera, Kin Two is larger than Kin One.
The phones are expected to hit the European markets in autumn while US will receive its first batch in May.
Microsoft's move to launch phones is being seen as the company's attempt to tighten competition for BlackBerry maker Research in Motion Ltd (RIM) and Apple Inc in the growing smartphone market.
When Microsoft launched Windows software for phones made by handset makers HTC Corp, Samsung Electronics Co Ltd among others six months ago, it was considered as an assault to Apple's iPhone and Google Inc's Android phones.
