If someone like Sonnet Technologies built a thunderbolt card for current Mac Pro would you buy one? I had a 1,1 version MacPro and sold it last fall thinking a new Mac Pro would ship soon. I do high end video editing so I created a SSD based MacBook Pro with thunderbolt display, Two Pegasus raid controllers and firewire 800 (which is only for backup as it is to slow for editing) Drobo, two Mercury elite 4tb drives. It is the closest thing I could get to a Mac Pro but is far from reliable. %50 of the time I boot I have to disconnect the thunderbolt cable, the system reboots every week or so. If someone built a thunderbolt card for a Mac Pro just for compatibility I would concider buying a speed bumped Mac Pro just to keep me going. Would you buy a thunderbolt card for your Mac Pro? Maybe a vendor like Sonnet Technologies would build one if enough folks asked them.
