Video shows how to use the Samsung GALAXY Note II as a PC
Multitasking, as you can see from the video, is entirely possible and the Samsung GALAXY Note II supports a more full-featured floating browser than the pop-up one found on the phone. Looking to tax the processor, two flash videos were started at the same time. With four flash videos running simultaneously with two native apps, things finally started to lag and break down.
2GB of RAM on the Note II. The 1GB of RAM on the OG Samsung GALAXY Note could not handle this test. S Note became a whiteboard-like tool, allowing the user to use the S Pen to scribble notes that could be seen nicely on the larger monitor. How did the Samsung GALAXY Note II hold up for PC game playing? Most games worked without a problem. One in particular suffered from a permanent portrait orientation, which looks pretty horrible on the monitor. Another game, called Nova 3, had a problem with frame drop. And lastly, plugging in a USB stick directly into the Samsung GALAXY Note II allowed the user to watch Misfits without a hitch. Trying this particular test with the Samsung Galaxy S III and Samsung GALAXY Note resulted in some contrast issues in scenes with low lighting.
The bottom line? While it might not be "practical" to use the Samsung GALAXY Note II as a PC, considering the extra accessories you would need to make this work, it is possible. Considering that much of the testing did not work with the OG Samsung GALAXY Note, a huge step was taken with the higher specs on the GALAXY Note II. Imagine where we will be in, say, three years from now.
