To sell a computer today is not very difficult. But to give the user a total experience that the computer he has bought is actually working as expected is often a whole different matter. For how much can you expect from an incredibly powerful processor in a computer when the "opening" to the processor is still just designed to deliver half the data power which the machine is actually able to deliver. This is truly increased efficiency: with a MicroMemory module you get much shorter waiting times, a better work flow and a general satisfaction with fast updates on your screen, preventing you from loosing concentration. This should be a good investment - for everybody.
