The Canon capture can fire from laptop or camera too. As well you can change the basic camera settings from the laptop. At least on the 5D though ,you cannot do a mirror lockup fire from the computer, which I find annoying.
*****Is there a capture setup that allows for RAW files to be written both to the CF card as well as the computer simultaneously? Since I shoot complex setups on the road, I am very interested in simple forms of backup that minimize hardware. Canon capture does this, Capture One does not.*****
