Not in Europe they aren't, here even as "Deal of day" they hardly get a buyer on consumer shops, always stuck alone in a dark corner of the shop, if they are there at all.
I travel regularly around central and southern Europe.
So far the only consumer shops I ever saw them on sale were the Media Markt, Saturn, FNAC chains.
Usually they have like one or two devices on show, and quite often with some kind of discount deal.
It reminds me of the Netbook Linux days, when such deals would be going for weeks until finally someone bought them.
