Same here. Except you have to realize you will only see the huge benefit when copying or reading large files. But from where or to? Internal drive is already capped at 6gbs. I guess another array of SSD's, but then you are capping the TB port. I think when the new Mac Pro comes we will have some amazing power. I'd guess more than one TB chip and hopefully internal SATA III.
I think I'm just hoping for creativity with the TB port. Display docking station (TB cinema display) is a great start. But imagine a TB display 27" or whatever. You hook your laptop into it and play games because the display has an incredible video card embedded into it. Laptop fans don't even turn on. You know?
I'm thinking TB Retina display ever comes out, they will have to do this, because no mobile video card can power a resolution like that (well they can, just not smoothly).
I almost went with the fat macbook for 2x SSDs (256 or 512).
However, for the fat 2.6Ghz plus 2x 512GB SSDs, plus 16GB 3rd party RAM, you're pushing the $3,200 mark.
2.6Ghz retina, 256, 16GB = $2,500
I dig the size/weight reduction more than I thought (shoulder bag + DSLRs + laptop = sore shoulder).
Dump field photos/footage to the laptop.
Delete and dump to an external mass storage Thunderbolt RAID.
Transcode to Thunderbolt portable 2x or 4x SSD scratch disk for working projects...backing up regularly, deleting and occasionally reformatting when complete.
I don't have that kind of money yet, just thinking for the future.
That dream setup would be perfect for an MBP
and a 2x(+) SATA III RAID SSD Thunderbolt Mac Pro.
The rMBP can handle most things quite well...
But I agree, an external video card and hot-swappable hubs would be a great addition.
Video/photo/audio people all drool over the potential behind Thunderbolt, and Apple's refusal to update the Mac Pro for them is unbelievable. Portable and Desktop workstations need regular integration... not half-assery
Edit: Earlier post I thought would be perfect in lieu of a Retina Thunderbolt Display:
Thunderbolt Display Mini
$600-$650
Extra wide 21" with these exact same ports
Detachable base, airplay ready...3rd party battery packs
