The PowerBook and the first MacBook Pro were only matte.

A glossy option was introduced in 2006, but the MacBook Pro was still matte by default.

In 2008, the MacBook Pro case was redesigned, and then the display situation changed significantly.

I don't think this is exactly accurate. The matte was a ~$80 upgrade option after they released the glossy. I definitely preferred the matte screens and still do. For coding reducing glare in uncontrolled environments is way more important to me than color fidelity, but to each their own.
