Android 2.2 (FroYo) took the Linpack lead for the most runs this last week. According to my analytics, Android 2.2 was used 43.1% of the time. Android 2.1-update1, the previous leader was used 39.8% of the time.  So what was used for the rest of the 17% of the time?  How about 158 other ROMs!  That is a lot of variety to choose. 

Mixed in with the lot is some curious ROMs; Android 3.0, Android 3.0.1 and Android 3.2
