With the iPhone 5 launch in the rear view mirror, numerous analysts have chimed in with their Q4 and full year iPhone sales estimates.

Amazon seems to have turned the tablet market on its head once again with the launch of their new Kindle Fire models.

All Kindle Fire models are said to be ad-supported to enable the low price point. As I predicted, the tablet price wars are now in full swing.

Nokia just unveiled the Lumia 920 and the Lumia 820, their long-rumored devices based on Windows Phone 8.
