Oh yeah. The number 9 is superstitious in some East Asian cultures, like the Chinese. Its pronunciation is similar to “unlucky” or “suffering” so people try not to use it, like some buildings skip the 13th floor. But it’s not unique. In Japan, the numbers 4 and 7 sound like death so they use alternative pronunciations. Another popular Asian belief similar to Astrology divinates personalities based on blood types.

Since Windows is a global product, MS execs decided to skip the number due to cultural sensitivity. They also wanted to close the gap with the Mac versioning and present it as a big improvement over Win 8, so it was probably a strategic decision for various reasons.

It’s simple: Ain’t nobody got time for your bullshit, Microsoft.
