It seems Google's Android operating system is starting to really pick up steam as it has just passed Microsoft for number three in the US smartphone market. Back in April, Android was behind Microsoft by the smallest of margins and now it has overtaken Microsoft. In April, Android held 12% of the market while Microsoft had 14%. In July, Android jumped up to 17% while Microsoft dropped to 11.8% which is a 5% gain for Android in those three months compared to a 2.2% drop for Microsoft. Android still trails Apple by nearly 7% though Android is gaining ground slowly. However, both RIM and Apple dropped during those three months, the same with Microsoft. RIM dropped from 41.1% to 39.3%, a difference of 1.8%, while Apple went from 25.1% to 23.8%, a difference of 1.3%. Android was the only platform to increase during those three months so take from it what you will. Maybe Windows Phone 7 will help gain some ground for Microsoft, but then Android 3.0 (Gingerbread) will be bringing support for heavy 3D gaming so it will be anyone's guess as to what each platform 's market share will be by then.
