Microsoft have recently updated their homepage (they’re moving the whole site to Sharepoint as part of the change). It is now a fully css-based page, albeit with an HTML 4.0 Transitional doctype.
Additionally some of the code is a little disappointing, for example instead of using heading elements they have employed classes:
<div class="heading">Popular Downloads</div>
Now, I’m guessing the Sharepoint might have something to do with this, in which case it isn’t a great advert for it.
On the plus side, I do like the design as it seems more task-oriented such as the New PC section in the Home User area, though this is let down by the slow response of the navigation, it just doesn’t feel right.
