1. Function limitation: Compared with notebook computers, tablet computers have limited functions. Tablet PC is based on mobile phone operating system and lacks professional software and functions, such as programming software, statistical software and image processing software.

2. Keyboard and input mode: Compared with the physical keyboard and mouse input mode, the virtual keyboard and touch screen input mode of tablet computer is not as convenient and efficient as that of notebook computer. For many tasks such as text input, writing papers and making courseware, it is more convenient and comfortable to use physical keyboard and mouse.

3. Storage capacity and expansibility: The storage capacity of a tablet computer is small, so it is impossible to simply upgrade or expand the hard disk like a notebook computer. A large number of materials, documents and course materials need to be stored during college, but the storage space of tablet computer is not enough to meet the demand.
