I’m just giving Internet Explorer 9 Beta a try, and my first impression is that the text in web pages looks blurry. See:
Top – IE9
Middle – Chrome
Bottom – Firefox.
I also tried to create this post using wordpress.com’s post editor in IE9, but it didn’t work – I couldn’t change the cursor position using my mouse, and the image upload dialog box wouldn’t appear. Which is ironic since Microsoft is touting WordPress’s IE9 enhancements.
