The new social networking phones from Microsoft, the Kin One and Kin Two will be available for sale starting tomorrow. At first the phones will only be available online, but will be in Verizon retail stores on May 13. The Kin One will be sold for $49.99, while the Kin Two goes for $99.99, and both require a two-year contract. They are priced that low after a $100 mail in rebate, which seems a little odd. The phones seem to be targeted at teens, but the prices seem a bit steep. Plans start at $39.99 for the cheapest Verizon Nationwide Talk plan, and require an additional $29.99 for unlimited data. I don’t know about you but if Microsoft is targeting a younger audience with these phones, they might be asking too much with the way they have priced it.

Microsoft announced the Kin handsets last month. The phones feature a custom interface focused on social connectivity. Both phones come with a full slide out QWERTY keyboard. The Kin One is smaller than the Kin Two, but both offer the ability to share videos, photos, and more with an easy to use interface. The Kin is seen as a less advanced smartphone, making use of cloud features to store data online. It does feature the Zune HD player for music playback, but it is not app-focused like the iPhone or Android phones.

While the phone’s target audience might be younger, many people speculate that Microsoft is overestimating the marketplace for the device. A recent survey found that most teens use text messaging more than they use data on their phones. The survey found that 72 percent of teens use text messaging, while only 23 percent use social networking on their phones. With the Microsoft Kin requiring a data plan, there might not be a very large market for the devices. Maybe they are hoping that marketing will bring people to the device, but as the video below demonstrates, they might need some help there as well.
