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
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.
