Welcome to the userboard.
I can tell you that you will get many different recommendations for this. I prefer workstations in each room. You get the most consistent performance especially if everything is wired. You don't have to worry about carrying around your laptop or tablet.
I think some will say laptops. I don't think that many use iPads. Obviously, with those two devices you usually have to use wireless. I can't speak more against wireless. You will get dropped connections.
In the end, it is up to you. Also, depends on whether you are going to finish your charts in the room, which I also recommend.
