What is more important? RAM size or Processor Speed?

Before most people buy a new smartphone or computer, they tend to invest more than just a few hours in researching about the hardware and software packages that manufacturers advertise. We all want a snappy experience along the life time of the device. RAM size and processor speed determine this. The question is: What is more important, RAM size or processor speed?

However, slow processor won’t do much even if it has more RAM to work with. A fast processor can’t function satisfactorily with limited RAM.
