I don't know if I'm more fascinated by this (btw, germany is the same, you get metric sockets w/1/4" or 3/8" drive) or the general lack of reading comprehension exhibited by those that replied. I would have assumed they would have just picked the closest size in mm (6/9/12).

These are all companies that started something good, but stagnated because they got away from a culture of innovation. The only thing left is to figure out whether Google has learned from this or if their article is 5 years down the road. I'm still not clear on that looking at what they've done post-IPO.
