By parity here I do not meant &quot;exact same feature set&quot; or even really &quot;equivalent feature set&quot;, but &quot;enough features to get the job done and feel like a real browser&quot;. For instance, Chrome-style JS extensions (~plugins) are coming soon enough.<p>Beyond that, if an enterprise has not gotten the message not to build LOB applications as browser plugins and not to build for one and only one browser model any time since IE6 has been deprecated, then IMNSHO they deserve what they get when IE11 dies as the last &quot;IE&quot;. Given the support timeline expected for Windows 10, enterprises have presumably roughly a decade of extended support to adapt before IE dies. Really hope enterprises are paying attention to that (but of course we know a bunch will not and will complain in ten years about lack of support and those of us that got the memo today can proudly mock them then).
