Really silly article - I can't believe this made front page on HN. How many Linux users would use Internet Explorer? How many Mac users would use Internet Explorer 9? Probably not many, almost certainly not enough to justify the cost in time and dollars to Microsoft, and assuredly not the author of this post, who seems to just need to find something to pick on Microsoft about. I thought those types died out long ago. I'm neither an MS/Mac or Linux fanboy. As a web developer, I've used Windows & Linux professionally, and developed sites to work on PC, Mac, and Linux browsers (as many of us have), and IMO, we don't need more OS/browser combinations to contend with; instead we need the browser/OS combinations that we do have to behave in a standards compliant manner across those OS/browser combinations. IE9 is a strong step in that direction for Microsoft.
