With the latest PPC Flash player (modified to report the latest version number of its Intel counterpart) and TenFourFox, my 1.33 GHz 12" PBG4 running Leopard was quite competent, if not somewhat pokey.
I used Safari to play normal YouTube (because TTF won't), and it worked surprisingly well (with the quality settings at minimum, of course), and VLC to play everything else (which did well except for some really big HD720 stuff).
While I'd rather not use it for daily stuff, I probably could if I had no other choice, since it does pretty much 95% of what I'd want a computer to do.
The only big thing I'd miss is the inability to run Pro Tools or any other high-end, relatively current DAW software. I suppose I could find an old version of PT for PPC, though, but it's not worth the bother for me (for now).
