It doesn't need to be on the same side as the screen, though. Neither my iPad nor my Nexus have any branding visible on the front of the device. The screen's border is perfectly black. Even the hardware button on the iPad is almost invisible.
Sure, the iPad has a big apple on the back, but I never see that when I'm using it as I can't see around corners.
This. You already know you're using a Dell machine. There is not point to advertise to the user. You might want to advertise to everyone else and put it on the back of the lid, which is fine, but I just want a clean bezel.
It's the same annoyance I have with all the stickers you used to get on any PC, not sure what that situation is like now.
Of course it would be nice, but you can't seriously ask a commercial company to remove its identity from its products.
