Well, let's agree that IE10 does well whatever it is designed to do well. Cool. Now what? We have an IE10 browser that compares well with Google Chrome, Opera and perhaps Firefox too (I don't know the exact details about your tests that were making Firefox crash as often as you've claimed in your article). So is this the point where Microsoft takes on the real challenge? Will it go beyond its typical high-speed sales…
IE 9 users on Vista are similarly out of luck.
I won't be recommending IE 10 even to my clients on Windows 7 or 8 until they have an silent auto-updater and a frequent release cycle. It's the only way we'll stop IE's user base holding back the web.
