I found this confusing:

http://www.everymac.com/systems/apple/powerbook/specs/mac_powerbook190cs_66.html

The summarized description at the beginning says "Dual Scan" for the screen, but then further down it says "Active Matrix".

As far a I'm aware, Dual Scan is passive matrix technology. If I'm right, which section is correct, the summarized description or the spec listing?

Also, I'm already aware of this page:

http://support.apple.com/kb/TA21582

and I've already discovered two errors on it previously, so I really don't consider it to be a reliable source of information.
