The learning curve depends on what you are trying to do.

Linux is equivalent or better at basic things like web browsing, email and media playing. These can be done with the basic graphic interfaces provided with user friendly distributions.

The problems arise if you are dependent on microsoft office, adobe application or games and the linux alternatives are not good enough for you. (There are alternatives but they aren't as good for professionals). The game compatibility is greatly improved but it is still a faff.
