"Graphic design students require a variety of tools in their arsenal at all times, ranging from high-end laptops to smartphones
Most K-12 schools and higher-ed institutions, however, are focusing on the use of tablets. This is because designers are now able to use more of a ‘free hand’ in tablet use due to the availability of additional screen space. This is especially helpful in item personalization and logo branding, for mechanical engineering, as well as custom t-shirts or other commercial products, and perhaps most of all web design."
