Report after report, same old, same old: Android and iOS continue to kick everyone’s arse in the mobile market. The latest comScore report is out, and once again, these two remain the only ones gaining any market share. Android continues to lead the pack with 48.6% (up 2.3 percentage points) while iOS remains in second with 29.5% (up 1.4 percentage points). Everyone else continues to lose market share with RIM holding the third position at 15.2% (down 2 percentage points. After that it’s Microsoft with 4.4% (down 1 percentage point) followed by Symbian with 1.5% (down .1 percentage point). Overall Android and iOS occupy 78.1% of the market with no signs of slowing down.

comScore remains a leading source for measuring key mobile trends, and their latest report is giving me a sense of deja vu. If we look at the results from the three month period ending November 2011, it’s safe to say that not much has changed. Samsung still remains the top OEM with 25.6 percent of U.S. mobile subscribers (up 0.3 percentage points), followed by LG with 20.5 percent. RIM finished last out of the top 5 with a 6.5 percent share (down 0.6). As for mobile OS platforms, I bet you can guess who’s leading.
