I may be out of the loop but didn't know that Android had stuff for completely customizing the workflow
Now, on to finding a preset good-looking configuration that I can just steal without designing myself...
You can replace the launcher, which is what they're referring to :)
Androids home screen is just another app, and you can replace pretty much anything.
Your default phone caller app, camera app, and as mentioned the launcher. Even the default icon pack! I've already posted my Android customisation here, I'll see if I can find it :)
