[Craig Seeman] “I’d actually prefer that to the 17″ so I can buy use change adaptors as needed for the job at hand. For example, Express Card when I need it. Two Thunderbolt if I need two camera inputs for live streaming.”
But see, I do a lot of traveling with my MacBook. So now I get to add a rather hefty device to be able to plug in my thin ExpressCard into my backpack in case I need eSATA support.
Your ideal setup is not very practical or elegant for people, like myself, who prefer to travel light and self-contained.
I will absolutely purchase an Ivy Bridge 17″ MacBook Pro with ExpressCard, especially if USB3 comes with it. Otherwise, I’m staying put.
