Final answer:
Switching to a tablet is the best option for a portable system without the limitations of a notebook.
Step-by-step explanation:
If you need a portable system without the limitations of a notebook, your best option would be to switch to a tablet. Tablets are lightweight, compact, and offer touch screen navigation, eliminating the need for a separate mouse and keyboard. They also have built-in speakers and often come with larger displays than notebooks, providing a more enjoyable multimedia experience. Additionally, tablets offer a wide range of productivity apps and the ability to connect accessories like external keyboards for more efficient work.
By switching to a tablet, you can retain the portability you desire while overcoming the limitations you currently face with the integrated mouse, small monitor, and compact keyboard of a notebook.
