My computer guru advises "Basically the min spec for W11 is crazy over-the-top (I think there may be a climb-down from MS, but we'll see) as even high spec PCs don't qualify"
and
"as things stand, W11 is essentially a cash-grab for the PC industry (or so it seems to me) and a push by MS to require online accounts (a number of features are locked behind an arbitrary MS account requirement)."

Anyway Micro$oft say they're continuing support for Win 10 for a few years yet, so we can afford to wait and see what happens.

All the changes to the user interface seem another instance of Micro$oft's general policy of "if it ain't broke, mess about with it anyway, and if it confuses users that's their problem".
