"Pssst… Want to know what is inside the Creative Zen Vision:M? Here is your chance to take a look inside, and if you are daring enough, take it apart. Below I have provided step by step instructions on the teardown without breaking this portable wonder. Disappointingly, there is not an extra three millimeters to squeeze in a bigger two platter 60GB or 80GB hard drive. This goes along with the earlier discovery of the larger docking station inserts. It is possible however to replace the 3.7v li-ion battery. So grab a tiny screwdriver set (Phillips and flathead) and a pocket knife and you are ready to take your Zen Vision:M apart."
Definitely not something I'd try myself, but it's pretty neat to see the guts of my favourite media player.
