Gone are the days when laptops weighed a tonne and took up so much space. On-going advancements in the sphere of computer manufacturing has seen a lot of refinements in laptop sizes. For students and busy executives, portability is a core requirement. The easier it is to fit your laptop PC into a small bag, the better. Therefore, a laptop with a screen size between 12.5 – 14 inches and weighing between 1 – 1.5kg fits the bill. When shopping for such a portable device, it is often best to go for a notebook. A notebook is a personal computer that foregoes some functionality to remain light-weight and small. Notebook computers are sleek, typically weigh less than five pounds and are small enough to fit easily into your briefcase or a back-pack. An Ultrabook also falls into this category as they are portable and light-weight.
