My friend's laptop always shows TF2 like images 3, 4, and 5. He can't play it because firing a weapon = crash.
His is a low-end generic video card as opposed to a failing strong one, but still, same net results. I don't think he paid more than $10 for the entire Orange Box anyway (one of Steam's awesome super-discount sales), so we both agree it's more funny than tragic that his computer can't run it.
I'm liking pictures 6 thru 9. Someone ought to make a pick-up item that makes the entire game look like that, with those neon colors constantly moving like some sort of druggie laser show. Or Valve needs to make it a server-side option. That'd be sweet for some non-serious gameplay. :O
