I was just googling this new feature, and if you haven't heard of it, it's pretty slick. If you use Google Chrome for internet browsing, you can click a button and automatically send the page or link you were looking at to your phone where you can take it on the go. It works for maps too
Follow this link and it'll take to you to Google's code site. First install the ChromeExtension and then the APK.

From what I've heard, this feature ships with 2.2. I'm currently using a Froyo Rom, but I think it might even work on 2.1! You could try and let us all know.
