I didn't say sales tax was dishonest, I said converting back a tax included price into USD was, and explained why. Aside from US sales tax being much lower than european ones (as low as 0%) US prices are pretty much always displayed without taxes, so you're making the machine look 20% more expensive than it actually is as far as american viewers understand it. A fair quote would have been to provide the regular USD price ($4300 maxxed out, or $3500 for 1TB).

What they mean to say is that VAT is included in the price tag in Europe, so when people see the € number they'll say "and that's exactly what it will cost" whereas in the US prices are before tax, so we will mentally inflate the number by ~10% when we see it.
