I agree. For such a questionable product, 16% strikes me as high, even if it is only polling Apple fans.Wow. 16% buyers is a huge favorable percentage for such a not-really-known, expensive device. Apple should be thrilled (except of course we do not know the characteristics of the by-definition-not-random cohort voting).
I recall the Apple Watch also being questionable when introduced (though I think not as questionable as VP is now). There was a similar poll here when it was introduced. Then, 31% of respondents said they were getting the Watch. Yes, that number is twice as favorable. But if VP achieves only half the success of the Watch, that would be impressive.
