Uhhh...way to many hours by me spent watching Linkin Park stuff
There are countless videos showing this...but her are a few off the top of my head.
These videos show the making of their latest album (showing how the band members use their own rig at home).
MacBook Pro(s)/Powerbooks can be seen during their live performances as well. Here's pic of their performance at the Apple Store a couples days back (you can see 2 here)

so now for some that aren't at the Apple store...
the very beginning of
this video
and even dating back to the PowerBook days...
2 PB's can be seen at 25 sec
in this video.
as I said earlier, these are just some examples. Search up any live performance really, and you'll see 'em.
The band is also shown going on MySpace etc. on MBPs during their free time on various episodes of LPTV (search up on youtube)
EDIT: Realized the video in the first (and probably most important) link i gave you doesn't work anymore. So here it is on
youtube (3 parts, look for the other parts in "More From This User").
