Microsoft just released IE 9 Beta 1 which promises to be faster and standards compliant. We will see. But IE 9 has lots of competition from Chrome and Firefox these days. In order for IE 9 to stand out above its competition, it really needs to address security issues that has plague previous IE versions, as well as sticking with the tried and true industry standards.
In addition, IE 9 needs to keep up with speed improvements gained by Chrome and Firefox. For non-technical Windows users, IE 9 will most likely become their default browsers. However, most techies will most likely gravitate to a browser that gives them security, functionality and speed. That means usually either Firefox or Chrome.
Can IE 9 make a difference?
