Bah humbug! 
I cruised the internet burning up the IRC chats and the www on my 50Mhz 060 Amiga until sometime in 2003. My Amiga was only about half the speed of my Brother's 650Mhz Athlon Unreal Tournament Gaming Rig at rendering webpages and about 1/4 speed at rendering large .jpg images. It was hilarious.
Heh, Yeah I seem to recall that around 2001/02 or so, I thought that my 060/50+PPC/240 was about as fast as a ~400mhz celeron/athlon/win98. That's how it felt at least. When it became cumbersome to work with after XP came out, that's when I sold the card,backplane, and 1200 mobo.
There's nothing wrong with AmigaOS, is and always was lean and mean - it's just that today, with the prices that some of those PPC cards are fetching, I mean, if you stick to 060 sans PPC, you aren't really missing anything. I don't really regret buying one when they came out, but other than playing mp3s or an earlyish version of MAME, or imagedecoders, there wasn't much to make use of...
