After much internal debate, today I decided to finally install IE8 Beta 2 on my local development machine.
Unfortunately, my initial experience was filled with annoyance and disappointment.
After some trial, error, and Googling, I found that the Google Toolbar was the cultrpit and I needed to upgrade to Google Toolbar 5 Beta to resolved the crazy yellow warning. After upgrading, this error went away, and I was actually able to use the Google Toolbar, wheww...
I wasn't very impressed with the speed of the rendering as well. It did seem faster than IE7, but I guess I have been spoiled after using Google Chrome for the past week or so.
Stayed tuned and I will give you 'IE8 Beta 2 Pros' in my next post.
