I understand...hopefully it's as great on PC as it is for Macs. FireWire was so freaking finicky on PCs...some people had no troubles, some people had immense troubles (me included). Having to use very specific chips, fiddling with drivers and legacy drivers, installing and uninstalling...FW was just a giant pain.
I hope that the specifications for Thunderbolt are more solid, rigid, and more widely compatible than its predecessor.
When I built my audio computer, I used the Creation Station specs as my guide since I hadn't built a computer for a decade before that, and had lost touch with current hardware. I like the look of those machines.
