ie7 beta

just installed and tried. not bad. some simple first impressions:

1. integrated mozilla's tab function. good. 从善如流，知错就改。
2. a close button is place at each tab--a usability improvement, at least for me.
3. f11 full screen function. neat.
4. simple and get-to-the-point menu bar.
5. favorites center is more available, promoting its usage.
6. more rss feed friendly.
7. ie7 beta reported that they fixed most of the bugs recorded on http://www.positioniseverything.net/explorer.html. --lol! i remembered myself struggling with ie's positioning while i was still dreaming about tableless layout throughout those css files. 时过境迁，俺业已退出江湖了呀。
