> who really wants commercial results built into their desktop?

The distinction between the desktop and the Internet is going away. Some argue that "the desktop is dead"; I just think that it'll get more integrated.

I don't think that this is necessarily a bad thing, providing that you have adequate control over your own privacy settings and have a choice of providers (both large and small). An open source project that is promised to always remain so is the safest place for this, since you'll always be able to find instructions to turn things off if the defaults don't suit you.

I much prefer this over the world switching to web-based hosted solutions for everything.
