Certification list is useless from buyers point of view

Example: on http://webapps.ubuntu.com/certification/make/Dell/ there are several entries for some models.

I have been told (by hggdh on #ubuntu-bugs who talked to the certification team) that this is not an error, the different lines represent different SKUs (configurations)

As a buyer I then conclude that if a line in the list does not cover all SKUs, there are probably some SKUs (of the models listed) that are not certified. So from a buyers point of view I have no guarantee that a specific model will work (according to the certification criteria, whatever they are) with ubuntu, so as I buyer I consider this list completely useless, that is of course if the buyer actually knows all this. To an unknowing buyer, the list will not only be useless, but even misleading.

Now that said: See it from the view of the company: The (in this case Dell) put some investment into getting their hardware certified, the expected return of investement is of course that potential ubuntu users will use this list as a buing guide. As long as users/buyers is unaware of this bug, this may very well stil be the effect of the list. However if buyers knows of this bug (which they may now), the list will not have the RTO-effect that companies expect.
