Again something that you shouldn't have to do. Really the only things that I have seen on Windows 8 that I like are the new task manager and the new file copy. .
Maybe he will enjoy browse with the Metro Chrome version and read his email with the Metro Mail, in case you don't know Metro Apps run in sandbox, quite a nice feature no ?
Windows 8 as nice feature for files sharing, google "Windows 8 Storage spaces"....you will discover something very nice.
I will stop there to not look fanboy , I still found some very annoying thing In Windows 8 , but their is no need to replace the Start Button, the Start page do the job faster when you know how to use it, especially the zooming with the mouse wheel.
