It was a most satisfying experience, in contrast to the waiting time often encountered when trying to speak to a technician. I also was informed that all the information available to the Dell technicians is available online to the users of their product. Having worked with Windows-based PCs at work and at home since 1995, it is my perception that each machine gets slower and slower the longer one uses it. We are dealing with perceptions as I have done no quantitative analysis. I wonder if I'm alone or if the perception is indeed factual.
Machines do indeed slow down with age.
One reason is all the background operations which are being added by software as we go along. I usually advise people to reboot their computer at midday when this gets to be a problem. You will see all the hidden programs that your computer is running. At the moment my own computer shows 45 tasks presently running. When I first received my computer, the list was not half that long.
