Throw the MacBook through the closed window- Sharing not possible

Question

--skip intro?
--NO:
This is again one of the questions that should never be a problem with a machine that has such a good marketing that it is labeled as "easy to use" - NO it is NOT easy to use. And this is not the only issue I have with it AND I think of throwing the very expensive MacBook Pro through a closed window. From wake up from sleep issues to vertical and horizontal stripes through timemachine stuff and not responding ForceQuitApplication Windows I am about to believe that Windows overall is not such a bad thing. A simple shared folder should NOT force someone to post a question in a discussion. Overall I AM VERY DISAPPOINTED BY THE MACBOOK PRO AND MAC OS X LEOPARD! Why was I never asked by Apple how I liked it in some customer survey?
--YES:
I (MacBook Pro 10.5.4 Admin Account) wanted to share a folder (not the "shared" folder) with my girlfriend's MacBook 10.4.11.
In the Help of the System Preferences Sharing Screen is says:
"Sharing files on your network
You can set up your computer to share files and folders with other users on your network. You can set up your computer to share your entire computer with everyone, or restrict the sharing service to allow specific users access to only certain folders."
This made me believe that when I added a folder for example /Users/MyName/FolderToShare within the shared folders list, and for that folder set the User "NameOfGirlfriend" with Read & Write access (btw. also Everyone with Read & Write access) my girlfriend should be able to access (GO to server..) the newly shared folder as it says above in the Sharing Screen: "Other users can access your computer at afp://IP address..." (I also tries SMB)
WHY IS LEOPARD NOT ABLE TO HANDLE THIS VERY SIMPLE JOB ?????????????????????????????????????
is again the problem sitting in front of the machine? in front of my machine? in front of a machine in cupertino?

I'm assuming these problems are current problems and not something Apple has fixed through hardware repairs...
If you're having those sorts of problems (particularly the vertical and horizontal stripes comment sets off very loud sirens in my head), that strongly points in my mind to either a bad logic board or defective RAM or both, and with the display corruption bit, my guess would be leaning towards a bad logic board. None of those problems are in any way normal or typical of Mac hardware.
Trying to fix file sharing while you're experiencing display corruption, frequent failures to wake from sleep, and frequent random application hangs is like trying to fix your car stereo while the engine is on fire. While your MacBook Pro is still under warranty, run, don't walk to your nearest Apple store and get a genius to take a look at this thing....
