It's not an Apple thing, it's an Intel thing; presumably it'll be 
rolled out on PC hardware soon enough too (and I think if this had
first been introduced on (say) Dell boxes we wouldn't be seeing the 
knee-jerk skepticism from some corners that we are.)  It looks like
it comes built into the chipsets, eg, you wouldn't need a separate 
"thunderbolt" board.  

Whether it scales up remains to be seen, of course, but hooking up 
a bunch of machines to something approximating a shared PCIe bus 
with no additional hardware seems like it could be genuinely 
interesting, if it works like that.   If not, well hey, it's a fast adapter
bus, and faster data transfer is good, even if just to peripherals.
