I agree, if there is something you want, then tell the manufacture about it, as although it seems at times that they do not listen, it is in actual fact the opposite. (A lot of features added by manufactures come from the uses requests)
However there is one thing to remember, the large manufactures are global and consequently get feedback from all over the world, which means it takes time to assimilate all the information, before they can add the features that the vast majority of uses want. (Also new instruments normally have at least a 2 year development before being released onto the market, so the technology used is also about 2 years behind the currently available technology)
