An independent computer software servicing company has told me that all
tablets, laptops, PCs etc should be serviced about every 40 days. Are they
correct, and if so how much should one pay for this?

That is complete twaddle. Modern electronic devices are usually replaced well
before serious hardware faults have a chance to develop. Tablet computers
need little or no attention and providing you make regular backups, when a
problem occurs they can be reset to factory condition and restored to their
previous state. The vast majority of PC problems are software related and
largely unpredictable. They often follow the installation of new
applications. In most cases this can be resolved using Windows System
Restore but even in the event of a major system failure, down time and
inconvenience can be kept to a minimum by making regular backups. The
biggest threat to a PC or laptop’s well being is overheating and it is well
worth carrying out an annual check on the cooling system. This entails
blowing out the accumulated dust fluff, and cat/dog hairs from the fans,
vents and airways. You can do this yourself with an Air Duster, basically a
can of compressed gas, but to do it properly on a desktop PC you really need
to remove the lid. It is a relatively simple job, though, and something any
reasonably competent DIYer should be able to do.
