Needs to be USB not PS/2 I bought http://catalog.belkin.com/IWCatProductPage.process?Merchant_Id= <http://catalog.belkin.com/IWCatProductPage.process?Merchant_Id=&Section_Id= 201725&pcount=&Product_Id=164030> &Section_Id=201725&pcount=&Product_Id=164030 at work and what I do not like it when I turn my pc off, it switchs to the server. I would prefer one that does not use a systray app that you try to hide, but upon restart it is visiable. I would prefer like hitting cntrl 2 times fast or something like that.
