While it is different, Linux is no more difficult than any other OS.

While it is different, Linux is no more difficult than any other OS.

I'll disagree with that; it also depends on what you're purpose for using it is:

1. (general) the commandline UI is utterly unintuitive and the help-system is terrible (man).
2. (web-hosting) the file-ownership / file-permissions are incredibly brittle and fragile.
3. (development) dependance on archaic and/or inefficient and/or fragile tools [make, ./configure, automake] drag development down.
4. (development) dependance on text¹ as the lingua franca for programming is very deeply ingrained; even moreso than other OSes due to Linux's love afair with piping between utils an scripting.
5. (general) the perceptions that it is more secure than other systems (e.g. windows) can/does lead some to rather insecure practices.

For general-use the command-line for VMS is supposed to be vastly superior, as it is for security (I don't have a VAX, Alpha, or Itanium; so I haven't really been able to test).
For development, Windows is slightly better — but its incredibly hampered by the requirements of some SW packages for POSIX (unix-like environment) depending on the aforementioned ./configure, make et al.

¹ — Text is not a bad form for reading, but it is terrible for storage and computation of programs as it essentially surrenders all syntactic and semantic knowledge (which then have to be recomputed), and they can be accessed/modified by anyone/anything at any time, meaning that a perfectly compilable file may not be compilable in any subsequent compiling (and this is unknowable, again forcing the recalculation [compilation] previously mentioned).

One aspect of Linux I love over Windows is that the support community is not confined to TechNet or other Microsoft-supported entities. You can find Linux adherents all over the world who run their own little Wikis.
