Icaros is easier to install than any Linux since it requires hardly any setting up, but you had better make sure you have some free, unformatted space on your hard drive. It also requires a reboot after you run the installer the first time, since it only sets up the partitions the first time you run it, and detects them and continues the next time, after rebooting.
The installer is pretty straight forward, just select the device to install it to, optionally specify a size of the partition and if you want a Work partition, then after the reboot you run it again and it installs the whole system to your drive while you multitask and play a game or get a cuppa.
I've been using Icaros for a long time now and love it. I also use Broadway on some of my machines so I can keep an eye on both distributions and get the best of both worlds.
I'm going to have to try it out on a few of the PCs I have built over the last couple of weeks from spare parts I found in junk piles on the side of the road.
