Can't speak for PedalingWalrus, but I don't find mine hard to set up at all. I can fiddle with it forever if that's what I want to do, but I can also set it up in couple of minutes. Hardest part is selecting the location. Of course I used to spend some time selecting a location with ground tent as well, but I was looking for different things. To me, the thing with that set that makes it look complicated is the tarp. But really the tarp is as simple or as complex as you want it to be. Things like the poles help open it up when the weather is nice and you want to look around. Or you can bring everything in tight to ward off a storm, or find a middle ground so that your bike can come under the tarp as well. I used to use a tarp just big enough to cover my hammock, and it was very simple: a line to each tree and a line to each side, but a bigger tarp gives you a lot of options and can give you a nice, open area to relax even when the hammock isn't in use.

But set-up/take-down speed is not the selling point for me. It's comfort. I've never slept as comfortable camping as I have in a hammock. I've also never worried less about wet weather and uneven ground. I'm not sure I'd still be interested in bike touring if I hadn't found hammock camping.
