I was looking over some Instacast user statistics and I was baffled by the fact that already over 84% of all Instacast user have iOS 5 installed on their iPhones. Over the beta period this number was constantly around 10%. Around Oct 4 when the GM came out the percent increased to around 20% and on release day Oct 12 the usage increased dramatically. I just made a small graph to show the effect. Kind of amazing if you think that the same line on Android would remain flat at around zero.
