well, I have been worried mostly because users of LG Chocolate phones told me horror stories about sensor buttons poorly working.
Now my kid is playing with this newly bought "touch key" player and after a while it will be clear how reliable it is. Kid's first impression is positive, mainly because of "wow" effect
By the way, could anyone look at the links I posted above

And tell me what chip this player is based on?
