Here's some cool stuff I came across this evening:
- XML NotePad 2007 - new version of XML Notepad for browsing and editing XML docs
- Fiddler 2 - new version of Fiddler that supports HTTPS
- Netmon 3.0 - new version of Microsoft's Network Monitor
- NStudy - track your progress as you work your way through the .Net APIs
and my favourite
Have a good browse ...
