I'm inclined to agree with some of that is said here
My dad owned an imac DV400 G3 400, he has a reasonable amount of ram installed along with a 40gb hard drive. OSX 10.4.9 is installed and it runs like a dream. If you compare it to a wintel mac, yes it's going to be slower. But not everyone has the money to buy a new system. If you have the room, i'd recommend getting it. Max out the ram, install 10.3.9 and you'll be laughing. For surfing, email and other tasks they are great.
regards
