When purchasing a mini laptop, it is important to keep in mind the following features: 1. RAM: The more RAM a laptop has, the more data it can hold at once. This is useful for multitasking and speedy operation. 2. Processor: Laptops with better processors can handle heavier tasks and run faster. 3. Storage space: Mini laptops usually come with less storage space than full-sized laptops and shorter battery lives. 4. Display quality: Mini laptops tend to have lower quality displays than full-sized laptops, but they are still good enough to use for basic tasks.
