Exclusive: Nokia's Windows Phone 7 concept revealed!

Now Nokia and Microsoft is coming togather in the market with its new smart phone in the market. Nokia is mainly using symbian OS for its device. Nokia want to compete to other brand in the market like blackberry, Samsung, Apple iPhone.We have it on good authority that the technicolor phones on show are conceptual devices produced by the two companies.
There are lots of prediction are going on market how the device will, features of the mobile.

You shouldn't, therefore, go jumping to conclusions about retail hardware just yet, but hearts should be warmed by the familiarity of Nokia's new design -- the shape of these handsets is somewhere between its recent N8 and C7 Symbian devices and there is, as usual for Nokia, a choice of sprightly colors. The trio of keys adorning the new concept's bottom give away its Windows Phone 7 ties, but also remind us that the N8 and E7 are highly unlikely to receive any WP7 upgrade love. The best part about this whole discovery, however, might be that it confirms Steve Ballmer's assertion that the engineers of both companies have "spent a lot of time on this already." So, who else is excited about owning an Engadget-blue Microkia device?

We can compare Nokia Windows Mobile with other device running in the Market.

But this is conformed that Nokia Windows smartphone will fully touch screen mobile with lots of feature like we can run Microsoft Office, mailing system will be easy one , we can send attachment file easily. Screen size will be bigger one like Apple iPhone , or Samsung Galaxy , Nokia will be having more storage memory like 8GB, 16GB or 32GB with expandable feature.
