Now IE7RC1 is running on my laptop, and I am writing this post using it. After using it for several hours, it is so funny to find it looks like firefox so much.
I like it, it provides more features, such as:
1. can use ctl+D to select all in url box, no matter where the focus is.
2. can use ctl+W to close current window
3. fonts are adjusted
4. can use ctl++/- to zoom in/out pages
5. integrated RSS
6. middle click can open a new tab
7. tab browsing
Based on 1 day IE7 experience, it resembles firefox so much, as all the features above is what I like in firefox. It is also funny to find that Microsoft is pursuing usability following other companies, which seldom happened in the last decade, at least in such an important product.
