Isn't the same as sitting behind a full sized monitor behind a very powerful pc that runs circles around your samsung. Not to mention that a samsung (or an ipad) are not able to use much of the needed tools you get will a full working version of photoshop cloud. It doesn't come even close.
For professional use it's a no no. Same when talking about taking photographs.
Are you trying to compare a PC and monitor to a phone/tablet?
