Samsung blurred the lines years ago when they released their Galaxy Note calling it a "phablet" - a hybrid between a phone and a tablet. I am about to blur the lines even further.
I just upgraded from the Samsung Galaxy Note 2 to the Note 4 and love testing how far I can push it. Using it with the S-Pen is Phab-ulous; however, why not add a bluetooth keyboard to make it a micro laptop?
I was just on Amazon and found this great set up and going to order it now!
