I am testing it right now and it is SUPER....
Here's the latest from OMG Ubuntu....
Software Centre
One of Ubuntu’s most defining additions is undoubtedly the Ubuntu Software Centre and Alpha 3 sees the maverick market place refine itself.UI changes we saw in Ubuntu 10.10 Alpha 2 have begun to take hold in Alpha 3 particularly with the new look store front housing feature and ‘new’ apps.
History
Whilst on the subject of the Software Centre be sure to pay heed to the much-improved ‘History’ side-pane entry.You can browse all installations, removals and upgrades by day or search. Right-clicking on an entry gives quick access to removal options.
Sound Applet
It’s one of the more controversial parts of the new Meerkat desktop - some people love it, some people loathe it.Either way it’s going to be there and, for fans of it, Alpha 3 brings a chorus of improvements including a working scrubber, working controls and the first steps towards playlist support.
Rhythmbox
Share your fave tracks with your friends directly from within Rhythmbox. Similar to the software centre’s tweet button you can tweet a link to your fave tracks via Rhythmbox.Users can then click on the link to be taken directly to the track in the UbuntuOne Music Store.
Shotwell replaces F-Spot
Shotwell replaced F-Spot as the default image management application.Time for a change
The new look indicator-clock has added a nice new calendar widget and preferences pane for easy configuration.
Messaging Menu
A neat left-aligned triangle overlay denotes running messages,and message counters are now rendered with a nice rounded background
Netbook Edition

Evolution Express and netbook-friendly versions of both contacts and calendar are also present.
The new ‘Unity’ interface is continuing to evolve at lively pace so the changes from Alpha 2 are considerable: new launchers, new applets, new apps.
Netbook bound Indicator-Network has received additions in both the settings window, mobile wizard and the passphrase dialogue
