According to an internal Apple memo (shown after the break), Apple is finally dropping the long-existing iPad purchase quantity limit of two units per purchase. The change goes into effect immediately at Apple’s Retail Stores worldwide (except in Hong Kong). The quantity limit is yet to be dropped on Apple’s official online store, but the change will appear on that digital storefront on June 11th, the date of Apple’s WWDC kickoff keynote. The removal timing likely implies absolutely nothing besides Apple possibly having enough iPad channel supply to remove a purchase limit.
