Okay. I'm not an accountant, but isn't the comparability of numbers always questionable, through different number of days in a quarter and thousand other reasons? Still we need to compare something, and why not the official numbers Apple reports? The guidance range for next quarter revenue isn't so good either.Apple simply changed the way it was accounting for certain revenue. The simply deferred $900 million in actual hardware revenue earned this quarter to future quarters in order to account for future software updates. That does not mean that they didn't earn the additional revenue!
