Yes I do. Here in France where AZERTY is the norm, whenever I manage to find and purchase another collectable PPC Mac, it has an AZERTY keyboard - which I've never really mastered but tolerate, and find no insurmountable difficulties.
Many of my other Macs have QWERTY which I prefer, but switching from one to another on a daily basis is a little like driving a manual gear-change right-hand drive car one day, and left-hand drive car the next. I've also done that frequently, and one gets used to it.
If I were you, I would buy the keyboard compatible with most of the typing you plan to do, i.e. if you will type a lot of letters, reports etc in French, buy an AZERTY keyboard. Then for leasure use, gaming, occasional e-mails etc, purchase a QWERTY silicon overlay with dimensions compatible with your model of computer. Then from the top menu bar, Apple/System Preferences/Language & Text/Input Sources, tick the boxes 'English' and 'French' and the 'Show input menu in taskbar' box.
You'll then be able to use either keyboard with ease, mapping either from the upper r/h taskbar.
