Should I buy the 4th or 3rd Gen iPad? Apple are selling the 4th Gen 64GB for €709 and the Apple store near me are selling off their old 3rd Gen 64GB iPads for €619. Should I go for the more common Dock Connector and save the €90, or is it better to go for the 4th Gen with the more future proofed lightning connector and the faster A6X processor? Thanks
