The whole purpose for Intel pushing this is into the high(er) end graphics, gaming and video production world, which is ready for this move, myself included. Why settle for 5 when I can get 10 and all the other advantages? I can tell you that even W7 based video production people like myself am excited to see Apple pick this up. If Wintel doesn't bring this to the laptop market this year, my next upgrade will be back to Apple for this port. Esata is not a solid connector (having just lost a RAID array to a cable falling out), and the ability to put multiple products, like dual monitors and/or higher speed drives seem like a winner.
