How do companies not get this? Don't call it the Zenbook [Impossible Number]. Call it the damn Zenbook and be done with it. No one cares that its part of the UX300 line, because UX300 means nothing, and you're only going to have three computers in the UX line anyway before you discontinue it.
But you know why they do that? Price matching. They can sell a SKU on Amazon for $700 and sell the exact same computer at Best Buy for $750. When you try to price match with Best Buy, oh whoops you're buying the Zenbook UX305-XYZ, that's the Zenbook UX305-ABC. Same hardware? Doesn't matter, different SKU, no price match.
