@Morkonan -- I agree with much of what you say. But I don't think grammar is all that important, as long as the message is intelligible. At least, it's not important for me. But then I guess I'm used to talking to people who are not native English speakers. I also don't insist that a vendor show their ability to make good renders. Many vendors get someone else to do the promo renders. Many don't even use Poser at all. Does not make their products any less fantastic. But I agree that great renders -- in Poser -- are extremely helpful, and the more, the better. As for gratuitous boob shots -- well, I'm not sure how well they work on women, gay men, and kids.

As far as grammar, spelling and rendered promos goes, it's more a question of "Implied Quality." Implied Quality is important in a commercial environment where competition is strong. In industrial/professional environments, where quality is spelled out in the contract and in the esoteric knowledge of the users, manufacturers don't have to necessarily put fancy labels on the box. :) Their quality is in the design specs or marketing literature. But, in a commercial shelf-space situation, one needs to push that implied quality as much as possible. Two products, sitting side by side, one that has great renders and emphasizes the sort of product and quality you're looking for, while the other does not... Which one will you pick, all other things being equal?
A note on "boob shots" - Women pay attention to those just as much as men, sometimes even more. Studies actually prove this. :) (Will reference if necessary.) Past that, there are variables that differ, per person, regarding how specific sorts of content will be reacted to. But, for just about everyone, male and female, "boobs" are always an eye-catcher. That is why marketers use such tactics so often, especially with intangible products that have little or no actual physical representation. There's a reason why chewing-gum commercials have buxom babes running on the beach in bikinnis and don't show sets of teeth clacking away at barely maleable tree sap... :) My only argument is that they shouldn't be what is focused on for product promos that don't have much to do with them. Certainly, not for primary marketing promos. Incidentals and inclusions, though, are fine, so long as a basic focus on quality and communication in these sorts of images is maintained.
