Well, obviously it needs to be switchable, and it certainly will be both in Linux and in Windows. Not so much in Google OS, obviously.
Again, I'm not voicing my personal opinions and preferences on whether and how I want to see search integrated into a desktop OS. I'm arguing that Bing won't go away because the current industry trends require Microsoft to have a reasonably good search engine under its control.
As for local searches commingling with online searches, there are some cases where it makes sense, others where it's a blatant violation of privacy, and many more in a subjective grey area. It's basically a matter of making sure people are informed (really informed, not small-print-in-the-legalese informed) and needing to opt in, not out.
It does on Ubuntu/Mac OS.

Shame nobody actually does this though. Also, does opting out actually stop the data grabbing, or just hide those results?
Personally, I think that's just bad ux, it's simplification one step too far. The user might not want these search services to know they are searching for some terms. That's a distinction that I know many users clearly don't care about though.
No, it shouldn't. Some people care about their privacy.
I also hate this fascination with search in general. If I want somefile, I know it's in Documents/stuff/foo_project/ ; I don't need to search for it.
