That is an interesting move for him. Given the amount of time Siri seems to go to the web for search it seems like Apple would reasonably want something in house to better manage the user experience.<p>My understanding though was that Apple's relationship with Microsoft was covering that (see this : <a href="http://news.cnet.com/8301-13860_3-20006971-56.html" rel="nofollow">http://news.cnet.com/8301-13860_3-20006971-56.html</a>) while tentative it seems another tie to Google that they probably don't want.
