Sparrow!
A new desktop app for Gmail. At first glance it’s great, it’s kind of like Tweetie for email. It doesn’t have all the full controls that Gmail has (yet) but it’s great in its minimalism.
Multiple Account Support is probably one of the best features:

One of the only things I’m having a hard time getting past is that read messages are still bold. Even though new messages have a round, blue icon as an indicator it’s hard to see what you’ve read and haven’t read at a glance.
