When it comes to Honeycomb specific apps, the selection isn't huge, so when you can score some for free, that's always a good thing. Honeycomb app dev Chris Stewart decided that he was in agreeance with that idea and has relinquished the price of two of his HC apps - TweetComb and Newsr - to display that.
As its name suggests, TweetComb is a Twitter client designed specifically for Honeycomb. While it may not be as good as say, Plume, it's really hard to compete with the price (even with the free version of Plume, you have deal with ads, whereas TweetComb appears to be ad-free). It offers the basics that you would expect from a Twitter client - real time streams, user-definable columns, support for multiple accounts, background updates, bit.ly support, sharing, and much more. Have a look at a few of the screens:
Newsr, on the other hand, is a very clean RSS reader designed specifically for Honeycomb. It syncs with Google Reader, so you don't have to deal with seeing the same article twice. It offers quick sharing support for Facebook, Twitter, Gmail, and more. It also serves up flash content right in its own browser, so you never have to navigate away just to watch a video. Here are a couple obligatory shots of Newsr:
If you've already purchased either of these apps, no need to feel duped - Chris is offering full refunds to existing customers, all you need to do is get in touch with him and request it.
