15 years ago I'd have agreed with you. However, there comes a time in your life when playing with your tools becomes less fun and you want to just get down and use them. I've gotten to the boring stage of my life when I am happy with Ubuntu LTS, because it means I can opt-out of a week of less productivity every six months when a new version comes out and breaks my workflow by forcing me to work around some "clever new idea" that won't last another couple of years. I'm sure Linus is even busier than I am, so I'm pleasantly surprised that he takes the time to experiment with and evaluate new distros and environments as much as he does. That's probably not what he wants to spend his time doing though, and not where he's most productive.
