I always wondered about CPU slot architecture, if you actually get the same performance out of it as if it were surface mounted.
AFAIK, Slots tend to be more (electrically) noisy than sockets.
This means you have to run the memory slower to keep it reliable. The best option is to include DIMM slots on the CPU card.
How much of this applies to the current Peg design I do not know. I am unaware of any drawbacks in the Peg design. ;-)
