(If you’re excited, it’s worth checking an hour or two before those times.)

The IE9 download will be available from and the Microsoft Internet Explorer page. I’m sure I don’t need to remind you, but:

Most of us have experienced the beta or release candidate versions of IE9 so there are unlikely to be any major surprises. However, this is the first version which most home and business users will install. Whatever your opinion of Internet Explorer, it remains the world’s most-used browser and IE9 will become an important part of your development life.

There are several important questions to ask yourself:

  1. Should you install IE9 now or wait until a significant proportion of clients have migrated?
  2. If you’ve been holding off using HTML5 and CSS3, is it now time to start investigating those technologies?
  3. Which modern technologies can be used in IE9 and — more importantly — what’s missing?
