@blowdart: They did improve searching, if you search for "everthing about .net" is will no longer try and access a .net address.
More importantly, you can designate you're searching by prepending a '?'. Searching for ASP.NET is now possible by typing "? asp.net". As far as I'm concerned, this fixes the "onebox" (really?) and I'm content with losing the seperate search bar.
