since we both own Sony PictureBooks, we KNOW what squirrely devices they
are.

laptops in general do not use 'standardized' parts beginning with the
motherboards and in general, are much more prone to breaking an install.
They do not sell in the numbers or have the longevity of design that
allows developers to accommodate their peculiarities, which can be big.

I'm not arguing with your methodology but rather trying to point out
that your usage is probably untypical.
