"So what do you think regarding this info?" Infringement on a rocker switch? I guess it will be up to MSFT to produce their documentation if asked. I think it's nice that the conversations are happening beyond our little world here and that they are about such things as the interface. I have commented in the past on the issue "Vinny" brings up....how many ways can a rock switch be devised? One thing is for cretin....when e.Digital is involved in a development...such as the Zune...questions are not asked of the interface or the underlaying technology. e.Digital has the documentation of ownership. doni
