Decrease in some tech searches shown by Google Trends

Do we have smarter searchers?

I didn't notice this up to today. But for many, many terms on computer science or PC terms, looking the graph from 2004-2006, there's most likely a noticeable decrease in search volume.
My simple question: why?
Might it be because geeks now know where the good stuff is and don't need to search on Google, and just go directly instead?
What do you think?

Look!
Hardware:
[google.com...]
[google.com...]

Software or tools:
[google.com...]
[google.com...]
[google.com...]

Even digital cameras is going down:!
[google.com...]

Some of these might have a little peak on 2005, but they fall in 2006 more than they were in 2004.

Yep, but the p0rn search is up.

I guess things are really going down hill.
