"is it really THAT big of a deal that this guy's work may contain some misspellings?"

IMHO it is, especially considering how trivially easy it is to correct these misspellings. What is more bothersome is not the presence of misspellings, but his acknowledgment that he has a problem, but steadfast (and even arrogant) refusal to fix it.

To me this suggests a "good enough" work ethic, which honestly doesn't inspire a lot of confidence.

That being said, I'd probably only apply this sort of judgment if I was thinking of hiring him or buying from him - it does imply a lack of attention to detail, a rejection of things that others consider basic competency, and an arrogant attitude.
