I shoot tethered a lot at work, taking macro shots of samples before and after destructive testing. Find for this work that the DSLR approach is simpler to use than the photomicroscopes in the lab. Use a salvaged cross-slide mechanism with a plate to mount the camera to for adjusting height above the specimen stage. More stable than any tripod. Just use EOS utility for this as it does all that is needed.

I've also played around some with the time-lapse feature at the beach and other locations. Just use a laptop for that to allow portability. Have never tried using anything but USB cable as I am quite reluctant to leave my equipment out unattended.

In a studio situation, wireless tethering should have advantages over using a cable with the primary one being increased range compared to the USB cable length limit. In the winter time, it could allow you to get some great shots at the slopes while you are cozied up the fireplace with beverage of choice in hand. I think you'll find that the possibilities are limited by your imagination and willingness to be some distance from your camera.

Congrats on the win. Think you'll have lots of fun using it.
