Efficiency Must: Get a Bitchin Back Button
For all you efficiency, speed demons out there starting businesses.
I once had a mouse without a back button. Now I have a mouse WITH a back button (and a forward button as well). I bought one as a result of seeing my friend use his mouse with a back button. It allowed him to insanely quickly rifle forward and backward throughout the interwebs. And if you love efficiency and speed (like me), you MUST drop that old mouse of yours and pick up one with a backward and forward button. Once you do, you’ll never go back. Trust me.
