The riocar is an amazing unit. Saying it should have had even more features was a bit hurtful.

I don't think it was hurtful for him to say "I think the product would have been more successful if X", which is essentially what he said. Everyone has a right to express an opinion.

I just think that sometimes people jump onto a BBS or mailing list and post their opinions too quickly before researching a little more. I think he's simply incorrect in his opinion of what X is. Knowing how the product was developed, knowing what it took in terms of manhours and hard-costs to make, I don't think they made any bad choices putting it together. If he'd known the history or spent much time with the unit, he might have had a different opinion.
