Not forgetting a little Google observation

This one almost slipped under the radar screen last week. Again, from Ars Technica, it covers Google's introduction of Google Desktop Search 3.0.

Should we be cynical? If you consider the explanation behind some of the new services, then on the surface perhaps we shouldn't. But this is as slippery a slope as there is, surely? And, even if we trust Google to do only good with our data, can we trust everyone else? At what point will we wake up to find we haven't paid Google a cent, but we've instead donated our soul?
