The last great battleship of the once greatest British Navy, the HMS Vanguard was a large and very seaworthy vessel though, given its launch date at the end of WWII, it was quickly of less use in fighting the Japanese Navy. In fact, despite its huge size and significant armament it never once fired its guns in active battle. What was it use for? Other than a flagship and training, one of the most notable uses of the Vanguard was as the yacht for Elizabeth II when she went to visit South Africa in 1947. Steve Jobs isn't quite royalty, though he historically travels in style in vehicles much nicer than the other Vanguard Wojo is referring to.
