Well, I already have 2 lines of fibre optics going from front to rear
and wireless network in my van. Planning to install 2x pc
motherboards, playstation and some more network stuff into this
vehicle.  A mobile office maybe more than a camper.

If I ever want to have my office here:

I definitely don't want to start searching for new memory chip.

For many, yes I agree. For me its a nice feature for unnecessary
complicated stuff. It also might be that I was traumatised by the
electricity in former Soviet Union during beginning of the 90s when
there were lots of Finnish companies working with western computers in
western part of the country.

But even the stuff You listed here contain devices called "solid state
disks". At least iPods and many newer laptops. For these SSD devices
spikes in the power are more like continuous wear than just *ZZZAP*
and and a dead device.
