You dont understand Apple's operations.
They will 'appear' to care about this stuff to appease shareholders.
They only dedicate the best but small amount of resource and then scale once they are confident they have a 'hot' product.
Get over it guys, stop whining about Siri and understand how Apple operates.
They have everything to lose - they are THE TRUSTED brand when it comes to consumer electronics w.r.t being an incredibly valuable firm.
