Scott Watermasysk has a post a thought provoking read about his top five favourite developer API's. 

From these API's I have worked with:

• RSS.NET which I used to cobble together a rss feed from our build machine.  I combined this with a X10 light configuration to provide a visible tactile build status.
• Genghis which is just awesome for adding those bits to applications that MS didn't have time for.

I'd also rate:

• Log4NET - who doesn't need logging
• FileHelpers - because reading files is what it's all about in the end

The IE team has blogged about a bunch of strap-ons for Internet Explorer to enhance it's functionality.  Go have a look at their recommendations.

Personally I've been quite enjoying my IE7 experience.  At the moment my favourite feature is Ctrl-Q to get a preview of tabbed browser pages. This along with the Inline Search plugin, the Spelling Plugin and the various developer plugins makes a pretty compelling browser experience.  Your milleage may vary.
