The efficient way to do this is probably to setup multiple machines in parallel. My line of thinking is that you go out and buy three identical machines. Spend the two days messing with everything and get a laptop just the way to like it. Make a disk image of the first machine and write it to the other two. When something in the machine breaks, open one of the spares and restore work files from backup. For me this would take less than an hour. When you get to the last laptop buy three new ones. If it takes you two days to do this initial setup you should have to do that fewer than once every three years or so.
