>>LMAO.. Is a Herman Miler chair worth 10 or 15 times the price of a normal chair? To me no (I sit on one at work), but an expert can point out how it captured or will capture the market).

And we can review that expert commentary and reach a decision- even comment on it. Which is what I'm doing here.

>>BTW, how is pointing out a lack of experience to make an informed opinion an ad hominen attack?

I said it's an experiential fallacy: you don't need to write apps for a phone to comment on its sales figures or market success.

But since you ask, here's a definition from wiki: Abusive ad hominem (also called personal abuse or personal attacks) usually involves insulting or belittling one's opponent in order to invalidate their argument, but can also involve pointing out factual but ostensible character flaws or actions that are irrelevant to the opponent's argument. This tactic is logically fallacious because insults and negative claims about the opponent's personal character have nothing to do with the logical merits of the opponent's arguments or assertions.
