Yes I will elaborate, but will not waste much time as it is obvious that you don't really know much about PC OSes at all.
For starters you think Windows 95 was an OS and it 'revolutionised' the PC world, so don't start lecturing us about what Linux is and isn't.
Windows 95 isn't an OS and DIDN'T revolutionise the PC world. It was simply a GUI shell on top of 16 bit DOS which dates back to the first IBM PCs built. DOS was the operating system, Win 95 was just as shell, exactly as Win 3.0,3.1 and 3.11 were.
OS/2 was revolutionary for a whole bunch of reasons (32 bit, TRUE multi-tasking, built in speech recognition, etc) you can look up while you're finding out what DOS was (hint: it was before Win 3.11).
It also ran very fast on 486 hardware with 16Mb of memory. The history of it's demise is interesting but largely due to Microsoft criminal anti-competitive practices (of which they were finally convicted, but too late)
Linux is easy to install, but a completely different to operate than Windows, which is why it is not as popular on the desktop. 'Dependancy hell' drove me away from Linux as well as the difficulty in getting drivers for hardware.
Linux is a great OS, but not because it can do wobbly windows and other eye candy, Windows can do that as well as anyone.
I use my computers for real work, not just dicking around.
