Actually,it's going to upgrade to Android 4.4(See the video on Youtube:http://www.youtube.com/watch?v=8_WmS75VeM8 )
Again, January 2014, and launched with the obsolete Android 4.2. It's unacceptable to have devices launched with the obsolete Android JB in 2014. And not upgradeable to 4.4? Beware of Acer, they are cheap yes, but you'll be stuck with an obsolete system forever. Look for the Android 4.4 KitKat logo ALWAYS.
