"usb-support for remote shooting - works now."
It means that you can build your own remote control to trigger the camera. With a key ring torch or anything that provides 5 volts and has a button.
Unfortunately, I don't own either of the two cameras to try that "Canon capture" software, but let's see if someone else is interested. But thanks for the link.
The "which camera to buy" question is always difficult to answer; it depends on your specific needs and likings.
Maybe you can contact the developer of that software to see if the A720 is/will be supported.
