It's all about the best of both worlds: Android apps and Windows software.
From the article "Is Samsung Making a Team to Rout Apple?":
"Microsoft’s software still plays a big role in the business and consumer worlds. Tablets that can run Windows software thus hold a particular advantage. Being able to run Android apps just adds frosting to the cake, because Google has a far more massive library of mobile apps than Microsoft does. The expanded capabilities along with the more recognizable brand of processors could help all these companies push back against Apple’s (NASDAQ:AAPL) long-sustained dominance in the tablet market."
"The blend of Android and Windows could even turn the tides in the smart-device war. Recently, Asustek showed off its own device that was capable of running both Windows 8 and Android. The new crossover tablets may put up a strong fight against Apple and do damage to the dominance of the ARM chip designs in the mobile market."
"Samsung will also make a few traditional PCs using Intel and AMD chips. It’s not clear if any of the AMD chips will find their way into Samsung mobile devices though, so the company may not benefit quite as much as Intel. Microsoft and Intel are sure to benefit from the increased support and exposure, putting Apple in a difficult position, as it now has some of its greatest rivals — Samsung, Google, and Microsoft — all gathering together in opposition."
