I'm not sure if bittersweet is the right word, english is not my first language. But I think the bitterness of Mindstorms ending reminding me of the beginnings of our company could be considered sweet. So I would say it's a bittersweet moment. I have to admit, though, I never used Mindstorms and as far as I know he never bought mindstorms for his children either. ;)
