I have a great idea. When you make a genius decision like getting rid of middle mouse button, maybe inform the users on the box so they don't make the mistake of buying it if they use a 3D software, Adobe software, or know that you can close tabs using middle mouse button. Every mouse for the past 20 years that I've used has a scrollwheel that can at least function as middle mouse button if it isn't already set that way by default.
