iOS 5.1 adoption rate is really fast.
by Erick Diaz
Looking just at the OTA eligible users we again see a promising future for iOS developers. Nearly 80% of users are on the latest version within 15 days.
This is why I prefer iOS to any other mobile OS out there. I don’t have to wait for any manufacturer or carrier to allow my device to be updated. Android might be open, but is closed for updates.
