Almost There

I like that they wrap the Web client so you get all the goodness, plus a native shell. Unfortunately, I’ve seen a few issues:
1) It occasionally hangs when swapping back to it or between accounts. The screen inside the window is just blank and won’t recover without a force quit and restart.
2) Setting it as the default mail client seems to unset regularly back to Mail. Also, a specific issue: clicking to email a tweet from TweetDeck app totally fails and resets to default Mail, every time. Unfortunate since this is a benefit of a native client over the Web.
3) You can’t use standard browser commands like CMD++ to zoom or CMD+F to find on page. That’s pretty annoying.
4) Sometimes when opening a new mail, it just shows a blank window.

On the plus side, it is effective at multiple account management.
