Bonjour Vincent, bienvenue !
I have to smile because I call my kids "les crapauds", but anyway.. Welcome to Mobileread, you will have great fun and get plenty of very useful informations. People here are really nice, and funny too, I must say.
Regarding your lurking, the 600 is probably a good choice, you can't do wrong with Sony. But the lurking never lasts long here
