He's referring to the fact that linux is a command line OS, and command line generally IS difficult to learn, steep learning curve, etc.
That said, I'm a windows "fanboy"*, through and through. So no disrespect, but no linux for me, since I dislike command line anyway. So any OS change for me will likely be to Windows 7, if possible. I know 8 is almost as bad as Vista, so I'm avoiding that like the plague.
(* = Definitely *NOT* an M$ fanboy -- there's a difference between fanboying over an OS and fanboying over an entire corporation.
