Firstly the reason that you are unable to get use to Ubuntu may be because you are still in the Windows mentality. Unless you have worked with other UNIX systems before.
Ubuntu is based on DEBIAN GNU/LINUX
Linux was originally designed to model after UNIX system so logically all the systems look UNIX-like
The original UNIX design was not made to be user friendly
UNIX focus on reliability and simplicity in design thats why it was the choice of system for servers and university used it for learning.
The reason was because at that time computing resources were limited systems had to be arcane to be able to fit into the limited hardware. A Graphical System wouldn't be able run on the best computers and do high computational work at the same time
I think your distaste of ubuntu is probably due to the fact you do not like to meddle with files like /etc/fstab
/etc/rc.conf etc
Windows do have similar systems but is hidden from users eyes for reasons like propriety and commercial technology
The reason i like BSD (another UNIX like system)
Is the fact that it does not shield OS technologies from user eyes enabling you to learn more
And it is the choice of server for high traffic networks (yahoo uses BSD servers)
The reason they cannot oversimplify the system is because they would have have to redesign the system from scratch.
Oversimplification will lead to low versatility because there are many hidden setting is required for an OS to be able better accustom to their task (optimization)
Hiding some of them would render it less capable of other task like server system and ubuntu btw is already simplifying itself by alot
& Ubuntu is also marketed as servers
Also Ubuntu like all GNU/Linux was not designed as an OS by itself
For it to retain compatibility with the Linux kernel it cannot change too much
Ubuntu is simply a software package added onto a Linux kernel was not designed to be a complete OS by itself.
This is the main reason i dislike Linux distros
However BSD is designed as a whole OS by itself but the developers did not want to sacrifice simplicity for power so it is also not user friendly
Support for Linux is not to gather lots of customers unlike microsoft
They don't sell Ubuntu/Linux
They are willing to welcome whoever embraces it
And giving the rest a Free alternative
Support will surely improve
For normal usage Ubuntu is already able to perform without any issue
For power users I am sorry to say you have to pick up the knowledge to UNIX operation
Which is what i am doing on my FreeBSD laptop current. Cheers
