There is only one thing that I consider a problem with the home and end keys: the text cursor does not move. I press the home key and I start to type and the window goes back to the previous insertion point and I have text where I don't want it.
As far as the rest of the keyboard shortcuts go, they were designed before Apple had home and end keys on every keyboard, so the shortcuts should stay that way. It's not as if older keyboards will suddenly change to accomodate changes in the operating system.
Besides all that, it was a good six years after the Macintosh that the x86 world even attempted a unified group of keyboard shortcuts and they were not easy to follow. e.g. was control-delete cut or copy? maybe, it was shift-delete. I think that Shift-insert was paste. Those are certainly easy to remember.
I enjoyed trying to run around the office trying to find a word processor I knew how to work. Printing a document? F7, F3, control-P, right Shift-stand on one foot and hum the national anthem? Finally, I asked someone if I could use their Macintosh since there was no guessing.
I know it's tough for people who have been using Windows for a while but Apple did things with good reason. Switching can be tricky and the documentation isn't always great, but the design of things makes sense once you unlearn things.
