A bit off-topic - has anyone an example of some marketing material which says something like our product is not good at XYZ, have a look at our competitors product ABC if XYZ is important to you? Because if you are actually interested in solving my problem I do not only have to know what you can do but also what you can not do. So even if your product does not support XYZ you can still help me solve my problem by suggesting a look at ABC. You see this sometimes in conference talks - which can certainly fall into the marketing category - but in general every product is always best in class, world leader with all the check marks in the comparison tables.
