hello everyone

i want to start doing digital-drawings and storyboards for advertising, so im looking for a computer , but i dont
know what ist called. its a pc (laptop) maybe by IBM and you can draw on the surface with a pen, the screen
can be turned around, and the pc is black. size is normal, nothing to fancy, the pen can be inserted in the back of the computer.when i know the model, id like to get a used one on ebay.

also id like to know what theyre called, tablets?

thanks for youre help, and greetings
