The only things i never liked about mandrake are it's generally bad handling of removable usb memory sticks or cameras and the weird library and header locations. Often programs never compile without a lot of effort(programs that are generally fine in fedora, if only i didn't hate using fedora).
Those two issues are the only real issues i have with mandrake now and in the past, but i am still using 10.1 so the first issue may be finally resolved?, i am certain the second issue is not.
