Because then there would be people complaining about "information overload" and that the search is returning too much. There is rarely a single way that is satisfactory to everybody, but at least with the Droid, you do get the option (even if you didn't know it was there).
I think it is less about information overload and more of people going, "WHAT?!? GOOGLE HAS MY CONTACT INFORMATION PASTED ON THE NET?!?" I mean, some people are afraid of certain information they have put in that shouldn't be out in the public. While it is nice that G-mail has your contact information you can get anywhere, I think some people like it where not everyone can see it as well.
Your not implying what I think you are here... correct? And just to clarify this for any newbie that might run across and get the same impression I got from your statement... Just because you enable search to find these items (on your phone) does not mean they are put "in the cloud" or online in any way. It is just expanding what is available in the search results to include items from your phone.
Jay, it is exactly what I am implying...
And no, I do not foolishly believe that it puts it out to the internet, however, I have found, in the past, that 'common sense' is not that common with people. I have people who think the internet is down because they open up their web browser and see they can't get to their home page, when the home page is set to MSN or Yahoo and their site happens to not be responsive.
I have people who don't understand why the Corporate policy to change your password every three months is necessary or why a hacker would go out of their way to screw over their system. I seriously hear people go, "Why would anyone want to do that?"
I have people who ask me, "Why can't I send e-mail to this person?" when they get a System Admin Message telling them, exactly, why the message could not be sent to said person.
So, sorry to say this, but yes... I actually believe the reason they don't have it on, by default, is for people like the ones I mentioned above, the ones I have to smile and try nicely to explain exactly the issue (repeatedly), who could easily just assume that when you do Voice Search for something and it pulls up your contact information, the mind begins to go, "Wait... How did Google Search pull up information that should only be known by me along with the search I was looking for?"
It is sad I feel this way, but again, from experience, quite a lot of people are ignorant of things. I mean, how why do you think people still fall for the e-mail phishing ones? (Heck, I know one person I give a hard time about, who fell for the whole, "But the e-mail looked official and I gave them my information..." trick.)
