While I always tend to take all these user numbers with a grain of salt, the latest ComScore results are rather interesting and certainly worth noting. For the first time, Android has surpassed Research In Motion as well as Apple within the ComScore ranking period of the past three-months ending in January 2011. As noted by ComScore:

65.8 million people in the U.S. owned smartphones during the three months ending in January 2011, up 8 percent from the preceding three-month period. Google Android captured the #1 ranking among smartphone platforms for the first time in January with 31.2 percent market share. RIM ranked second with 30.4 percent market share, followed by Apple with 24.7 percent. Microsoft (8.0 percent) and Palm (3.2 percent) rounded out the top five.

While interesting to see, it's not really surprising in anyway. Android continues to grow and as more manufacturers step up to make use of Google platform a slow down in market growth doesn't appear to be in sight. While I personally shed a tear for BlackBerry, Research In Motion is in a transition period and will be for quite some time. This is an Android and Apple time now, with Microsoft working their way back into relevancy. [ComScore]
