Most of us can do it with ease, that leads me to say that it's idiot proof, but after I had the pleasure of talking with a young lady that didn't even have iTunes installed on her PC it made me realize it's not all that easy. Some people don't even know how to unzip the folder, and some don't even read directions. Even if you get past all of that you still have to add repo's and tweaks etc... and sometimes it can give you weird errors that for common users are almost unsolvable.
So I do believe it has a mid-high learning curve.
