One of the Nokia’s internal video showing the concept of how Nokia Air, a cloud service for mobile phonesÂ got leaked to internet yesterday. The video is definitely old, but it shows how Nokia had a vision of its own Cloud service on its Symbian/MeeGo Operating Systems. One interesting thing toÂ noteÂ from the above video isÂ the appÂ delivery system on Nokia Air. It seems like they are completely cloud based, i.e, every app is a web app, so its alwaysÂ up to date no matter where you are. Also itÂ reveals that Nokia really had plans for a tablet device. Even though the concept of Nokia Air is of no use at NokiaÂ at presentÂ since Windows Phone has become their primary OS, I expect them to make different form factors of Windows PhoneÂ smartphones and Windows based tablets as shown in the video above.
