Can't tell you how long we've been waiting to be able to view Google Docs on Android -- but that day has finally come, all without having to download the file (or even an app, for that matter). It's all done at docs.google.com from your Android browser. (Or iPhone and iPad, too.) And from there you can access all of your Google Docs. No editing yet, but viewing's better than nothing, right?

Edit: Yeah, so the Google Docs thing isn't that new. But PDF and PowerPoint support is. Better than nothing. We guess.
