What's silly about them (if picofuses are sensible)?

You and me both :-). To be fair, Amstrad did sell service manuals for the
machine at a sensible price. (THe one I have has 'Price \pounds 8.00'
printed on the cover), and spare parts  were available while the machine
was in production. So about 20 years ago you could have got a
replacement gate array chip with no problems. Which is more than you can
say for a lot of manufacturers.
 I had no problem getting a replacement flyback transformer for an
Amstrad PC monitor, for example.

I still think the nicest CP/M machine I've seen is the Epson QX10.
