On the plus side, I just started using Google Reader, which I recommend. It let's you subscribe to content from sites that have feeds (like this one). For example, to subscribe to this site, you'd enter this URL in the subscribe field:

Anyway, it's cool.

On the not-quite-as-cool side, they've just released their web-based app for presentations to compete with PowerPoint. Wired has a review.

Google Presentations may be gunning for Microsoft’s Powerpoint, but it still has a long way to go. Presentations can create a whole new slideshow or import an existing PowerPoint file and it has some nice collaboration features, but the inability to export files as slideshow (PowerPoint file) will likely be a deal breaker for many.

Yeah, that is a deal breaker. I've been impressed with most of Google's products. I'm not sure why they'd release this without an export feature. Also on the down side, there's a 10MB limit for imports, and something the article doesn't mention: It doesn't support OpenOffice formats. That's also pretty stinky.

And when I imported a test presentation, the formatting was pretty messed up.

Looks like they made this one publicly available a little too soon. However, the other Google Docs offerings are still pretty nice, so check them out.
