I actually enjoy doing clean installs. Sure installing all the software and downloading updates takes time and putting back all the files you backed up like my music, pictures and document can be time consuming but I love the new car smell (metaphore) I get every time I do it. It also allows me to clean up all the clutter and only have the latest updates as oppose to all the leftovers of the previous multiple updates of all my software.
I say do the clean install, it's time well spent.
