I avoided it for a long while because I didn't think it would be woth the hassle. But really it is super easy to install, it takes about 30 seconds.
Just open the Optifine zip up in one 7-zip window, open the minecraft.jar file in another 7-zip window, and drag the files from the optifine window to the minecraft window, then delete the Meta-INF folder from the minecraft.jar. Done.
You just have to do that every time there is a minecraft update though.
