Ask HN: Best examples of software welcome screens?

I had a look on Google, and couldn't find much. The welcome screen is for when you first load the software and it shows you latest news/info etc.

We don't want it to be a bloated and full of junk, but concise and clear. We like Thunderbirds welcome screen (although we are not going to do an HTML one) and also VS 2010 welcome screen

Anyone got any examples of really good welcome screens? And any advice/tips/resources for designing them? It's a really important entry point so we want to get it spot on.
