Leopard updated this morning

Leopard on the Macbook updated itself this morning. The IBM computer took some getting used to. I am still using Apple keyboard short cuts. I need to relearn or readapt to PC short keyboard cuts I found I could run Second Life under Linux. I also learned to use the Konqueror browser. I do need firefox for some web pages but so far can not install firefox under Debian using the Synaptic package manager. I also have not found K package yet I did just now while writing this post install KDM and may have KDE working soon enough. In fact, as I proof read this I was asked by the computer which default window manager I wanted to use and I selected KDM. I am restarting now and will see what happens.  I did not yet get KDE. I also in this install run/download installed numerous K packages. I also just got a DVD to play apparently violating some law perhaps concerning copyright. I downloaded some package that was a library for decoding DVD's. When I did this K package popped up. So with all of the above I am getting there with Debian Etch.
