Has the iPad been genericized in Chinese? The other day I heard this guy referring to his 平板电脑 as an iPad (爱怕德), when it was just some generic tablet computer.

Chinese contains a lot of genericizations, 可乐 for soda, etc.

Is this one too, now?
I think in this case, it's true

"iPad" is more famous, most people (at least in mainland) aren't familiar with digital devices. People maybe don't know what tablet computer is, but they know "Oh it's Apple's iPad".
