What kind of tablet computer is suitable for photographers?

I just started reading the e-book T4, which was ordered in official website. The electronic book T4 is operated by the electromagnetic pen on it. I think it is very convenient, just like the feeling of writing or drawing on paper with a pen, which can perfectly present the characteristics of our China people's writing. Text content can be modified by eraser, especially it is very convenient to edit and approve various documents. Suggest that the landlord also consider it!
