TweetDeck's new non-AIR client was a little lacking in features when it first came out, but today it received a major update that makes it much more tempting. New features include full support for Twitter lists, inline media previews, a new format for retweets, and more.
The inline image previews are arguably the best part of this new update, showing you pictures and videos inside the stream, without requiring you to click on a link. The new lists feature is nice if you're a fan of Twitter lists, though, and the new Activity and Interactions columns are an interesting way to keep up with your Twitter friends. They've also updated the retweet feature, now allowing you to use the "RT @username tweet" format rather than the less popular quote format.
Its filters still aren't as advanced as the old TweetDeck, and it's still missing a few of the AIR client's other great features, but if you've been waffling between the two, these new features might be enough to tip the scales.
