Indeed they're not PeeCee friendly, for the given reasons. I
don't see how they'll work, unless the market changes
drastically. LGA sockets are the pits, or are incredibly
expensive. I've paid upwards of $3000 each, for LGA/BGA sockets
that'll last more than 50 or so cycles (like the $50 variety).

Well, duh! This has been known for years. Again, I don't see
how this is going to fit in the PeeCee market. It works well for
ASICS, and even Apple. The PeeCee market is very different.

Glueing the part to the board solves that problem, but it sure
makes a heck of a mess of inventory. ;-)
