Note 10.1: MULTISCREEN TABLET:

Multiscreen allows you to run two apps at once on the same screen; however, the apps you can can choose from are limited to a specific six (S Note, Polaris Office, Video Player, gallery, Email, and the Android 4.0 browser) -- unfortunately you can't swap in any app you'd like. The thought behind the feature is to give you the ability to create content by pulling assets from one app into another. 

     With palm rejection, as long as the S Pen is in your hand, the screen will not feel any other capacitive parts of your body, in particular your palm. So unlike other stylus pens, where your palm disables the pen, with the S Pen's technology, you can place your palm flat down on the screen and still write to your heart's content.  

The most  significant hardware feature on the Note 10.1 is easily the S Pen. The S Pen looks like a traditional stylus and pretty much feels like one too, but differentiates itself from lesser digital pens. The pen's tip sports a pressure-sensitive sensor that recognizes 1,024 levels of pressure. Samsung says the original Note only got as high as 256. So, depending on the app you're using (not all apps support this), the harder you press the pen on the screen, the thicker the resulting lines.

                         There is a Wi-Fi-only version and a 3G-enabled model, both powered by Samsung's own Exynos 5 Octa chipset, as well as an LTE-capable tablet with Qualcomm's latest Snapdragon 800 chipset ticking inside.

Main disadvantages

Nothing is perfect,So it also has some pitfall that Samsung need to be more concentrated 

as it has

• No NFC
• No DivX and AC3 codec support
• Air view works with S-Pen only, no thumb support
• Notification area not optimized for the large screen

but all and all it takes the technology to the next level but To date, no tablet maker has completely nailed the concept of a work-capable slate. Is the Note 10.1 2014 Edition the one to do it? We'll discuss precisely that in the pages ahead.
