Slated for release during the holidays, Windows Phone 7 has gradually shown its face to the industry, and despite some negative press, most have been cautiously optimistic about the future of the mobile OS. The optimism must extend to AT&T as well - citing a "trusted source," technology columnist and analyst Michael Gartenberg tweeted that AT&T plans to receive eight million units at launch. To put it in perspective, that's almost three times more than the number of iPhone 4 devices sold to date, and as MobileCrunch points out, approximately one million times more than the number of KIN devices sold.
Microsoft has been exceptionally careful about what they've shown the general public, and when they've shown it. To that end, this shows that AT&T believes in the Windows Phone 7 platform - at least, they believe in it enough to sell eight million devices.
