(I use Ubuntu regularly and have never owned an Apple product.)
That said, really? It doesn't come with gcc anymore? I find this offensive.
Lots of Linux distros don't install one by default, and this has always been the case. For that matter, for a long time, Solaris (unquestionably a UNIX) didn't come with a compiler.
Different distros have different amount of compliance with traditional UNIX. Ubuntu is one of those which has ventured the farthest away from it.
