It's taking me way too long to get going on this again...???

i had a very bad experience with LINUX the past few days...!!!
Linux is supposed to be the hot new Operating System that is going to replace The Wintel and Macintosh Operating Systems... But i now have severe doubts about this... It is; i now suspect, just as Evil as the other two...!!!
---
The problem arose when i tried to download and install an HP48 emulator/simulator on my new MacBook, and there were some immediate difficulties... One being that i had to find and download a copy of an HP48's internal memory... These are somewhat proprietary and so you have to do that on your own... Which includes swearing to the website where i downloaded it from, that i own an HP48gx already...
---
So i think i managed to do that; But then amoung all the files that were allegedly the emulator, i couldn't find anything that looked like the application...???
---
So i went and asked the experts on the HP48 newsgroup, and then the real craziness started.
---
To cut right to the chase scene, i would need to know how to operate the Unix command structure underneath the Mac OSX, and execute a variety of commands to 'build' the simulator.
None of this was explained with the documentation that came with the simulator, and the experts on the HP48 newgroup thought that these 'steps' were so obvious that they repeated neglected to mention them to me, although my level and expression of frustration were steadily mounting over the course of about 3 days...!!!
---
i have officially given up trying to install this simulator.
It would appear that i would have to learn the entire Linux/Unix Operating System, just to have enough foundational knowledge before someone could explain to me, in any kind of reasonable way, how to get this simulator to work.

So that now:
The expression: "Gawd! i hate computers!" extends not only to the Wintel and Mac Operating Systems, But the Unix Operating Systems as well.

ugh.
