The 180mm f/3.5L was sold out by the time I looked at the link. It's okay though, I don't even shoot macro anyway.
And for those looking down on live view, the 180mm f/3.5L Macro that was on sale in best buy would be perfect with live view.
One of the main purposes of live view was for precise focusing for macro photography. Using live view compensates for errors of the eye. And for those who shoot JPEG, it helps get the correct settings quicker, as live view simulates exposure on the screen before the picture is taken (except when using flash). And shooting from the hip or from above is way easier with live view without having to guess where the camera is focusing or the framing of the picture. I personally use live view quite often when in large crowds and my subject is a far distance away, as it helps with my composition in less tries. Also when shooting inconspicously, I shoot from the hip, and using live view helps me keep the subject within the frame.
You may call it cheating, but it's just another feature that helps photographers like RAW, higher FPS, spot metering, etc.
