Important for 10% of the population

I'm resolutely right-handed. (And right-footed.) I play baseball, cricket, and tennis right-handed. (The only exceptions in sports are ice and field hockey. I hold those sticks left-handed. No idea why.)

So, I'm not all that familiar with the ink smudging problem that left-handed writers face. (By most estimates I've seen, about 10% of the population is left handed.)

While this is not an important feature to me, it must be important enough to a chunk of the population that Zebra felt it was worth mentioning. And good for them.
