Not that I would be jumping any beta bandwagon on my production notebook. But, encouraged by the feedback from some of my fellow RDs I gave it a try and am pretty excited about it.
- blazingly fast
- very stable (no problems, yet)
- easy to use
- maximizing the content experience
Unlike other browser and previous IE versions, IE 9.0 Beta shines by it simplicity and power. That is the way modern applications should be. Nothing gets in your way.
If you want to try, get it from: http://windows.microsoft.com/en-US/internet-explorer/products/ie-9/home?os=win7&arch=b&browser=ie
Be aware that there is no uninstall (which is not needed) and XP is not supported due to the hardware acceleration.
