What's with the odd name? Apple already has a 15 year-old product called Thunderbolt. Mozilla already has a similarly-named but totally-different product called Thunderbird.
Despite being a long-time Apple user, I just purchased an Android tablet the other day, in a large part because iPads are so locked down and controlled by Apple.
This decision will make me strongly consider returning it and getting an iPad instead. iPads leave Android tablets in the dust in terms of performance, although I do like the microsd card slot on Android.
Of course, it could take years for Apple to reluctantly implement the change.
