Watching the video that coldtea posted, no, it is not. Ubuntu and most of its derivatives have very easy installers, and take a fraction of the time. The video didn't even include the time it would take to read and understand all the terms and conditions!
I don't know what you mean by this- care to elaborate? I have several fully working computers running Ubuntu derivatives without having to do anything after the install.
I currently have two laptops, one a Lenovo from work with Kubuntu and the other cheap Asus with KDE Neon. Both required no additional work to be fully working after install.
