I was encouraged to see that Motorola recently decided to drop Windows Mobile from their future cell phone offerings to focus on Android. 

Now Robert V. Green of the well-respected investor website Briefing.com writes in an article published today that he believes Android could seriously erode the Windows monopoly over time. 

Based on our own experiences using Android on the HTC G1, we'd say there's a long way to go before Android replaces Windows on the desktop, but it's nice to see the investment press taking notice.
