I feel like there's an obvious answer to my question, but as usual it eludes me

There are a few gadgets for which I am eagerly awaiting news. The Nexus Prime/Droid/whatever, the Tivo Preview, and a couple others. In the last month or so I've started to get extremely busy and it's been hard - even with my beloved Galaxy Tab - to keep up with Engadget.

How can I set up some sort of keyword search to notify my of breaking news on such specific topics? Is there an app for this? A desktop application?

Ideally, I'd get a notification in my Android notification bar that would tell me if there were a breaking story on one or more sites for the keyword(s) I specified. I would accept email alerts as well, but not texts (I hate texts ).

Is there a way to do this? I'd guess there are a couple RSS readers out there that could do it, and while I'd like to avoid using one because I'd have to keep my computer on at all times, I might consider it.
