The problem with PCs is the upgrades needed.

I was thinking about mobile gaming the other day and how crap the games actually are if you compare them to what else is available on PC or console. Essentially, mobile gaming has saved gaming companies from needing to produce anything new as a basic platform game is good enough. They can just rehash old shot with new characters and people will pay 5 dollars for it.

The console gaming life is one of eternal user as there is so little that can actually be done by the user to change the experience. As you said, "comfortable lay back and play with a controller" - and learn nothing more.
