That sounds like a cool deal. The "Better Together" combinations on Amazon.com seem to change quite frequently. A few weeks ago "Rich Client Programming" could be bought together with "Harry Potter and the Deathly Hallows (Book 7)". And then a week back one could buy it together with Adam Myatt's Pro NetBeans IDE 5.5 Enterprise Edition.
So, if you're interested in filthy rich clients, better snap up this opportunity while it's there! Click here to get to the site.
