I also use debian today.. I really love the package system and the control you have there :-D
I am really not sorry for that i started with mandrake though.. I really dont think i would have used linux today, if it was not for the experience i had with mandrake..
I think mandrake is a real nice way to get to know linux. :-)
One tip though... Make one dedicated partion for /home, as then you will have all you programs/documents untouched, if you decide to change distro later on..
