The flip side of an electronic device like the iPad (as opposed to, say, watches or books) is that over decades, it is likely very to deteriorate to the point of destruction.
Not necessarily the case or screen. But the battery inside is essentially a plastic-wrapped slab of acid. Which will
eventually eat its way out, spilling into the inside and turning most unused iPads into discolored, hollow shells.
This will be the inevitable fate of the millions of iPads that
don't end up in landfills, or shipped to some toxic hellhole in Bangladesh or China
for recycling of e-waste.
One could, of course, prevent this grisly fate by cracking open the iPad, and removing the battery before putting it into long-term storage. But this does sort of raise the question as to whether or not replacement batteries will be available thirty, or even TEN, years from now.
So, a shrink-wrapped iPad sitting on the top shelf of your closet for thirty years or so is very unlikely to be in working, or even usable condition. And a collector of
fin de Millénaire electronic relics in the year 2310 is likely to be as disappointed as was the
wine collector who bought the
Jefferson bottles in 1985.
