Re: IE 7

It is not ready for prime time (and may never be), it is still in beta
release.

And from this thread:
http://groups.google.com/group/alt.html/browse_frm/thread/6f3d91df997ffd62/71468152597ee184?lnk=st&q=IE7&rnum=10#71468152597ee184

IE 7 beta 2 is supposed to be released in 1st quarter of 2006 according

to IE7 blog.

But already, you can be sure of several points, as these were
officially
announced by Chris Wilson:
- MSIE 7 final release will not pass webstandards.org's acid2 test
- MSIE 7 final release will not be available for Windows 2000, ME and
Windows 98 (which represent approx. roughly 40% of the current Windows
users)
- MSIE 7 final release will not support "application/xml+xhtml" MIME
type

- MSIE 7 final release will not fully comply with HTML 4.01 regarding
its implementation of <object>

For many reasons, I believe MSIE 7 final release will still be behind
other browsers (Firefox 1.5, Opera 9, Safari 2.x) support for CSS
(including CSS3), DOM 2 support (possibly Events interface and other
interfaces) and possibly accessibility features.

In all fairness, it is too premature to claim that MSIE 7 will be
surpassed by other browsers but, at least in some particular areas, it
will be lagging behind other browsers.
