of anyone is interested My PGR ASTRO IIDC shots of the Venus transit from

Thanks for a great product Milton.  I shot 200 frame .movs on a manual backpack mount in 30mph winds on the side of a volcano and the software stacked all 300 movs without coughing..

I'd have to agree, especially on a cost basis.

Both Apple and Intel have been dragging their feet on USB 3. I suspect
it's because both don't generate royalties or have such tight control
for USB 3 like they do for Thunderbolt.

That was one of the main issue with FireWire too - purchasing
documentation was (still is - the 1.3.2 IIDC specification costs $300
USD for about 1 page of changes from the IIDC 1.3.1 revision) and the
per port royalties drove the cost up dramatically compared to USB.

And I have read and had a few customers tell me that Thunderbolt to
Express card is not a good user experience at all. Flaky performance,
odd quirks in what cards are or aren't supported and stability issues
seem to be the norm rather than the exception.
