I mean, a laptop case is specially made for carrying a laptop but a backpack is just a bottomless pit. So how will you ever find anything in a backpack?
If you intend to use the laptop from home a lot, then I’d go for a 17-inch wide screen. If you are more concerned about portability or if you travel a lot, then laptops with screen sizes of 12.1 or 13.3 inches might suit you better. There are also 14.1- or 15-inch screens for Naprawa komputer?w, but I believe manufacturers are shifting away from these models.
Internet connection. One has to be in touch with the rest of the online community. There are wireless connections offered already. To one with budget constraints, an ordinary 56Kbps modem would pytania do sprzedawcy laptopów to connect to the rest of the world.

Use on flat hard surface Laptop is a very compact computer where there is minimum space inside the chassis to release heat. Most of the time, heated air is ventilated out from the side and bottom of the laptop. By placing laptop on top of flat hard surface, heated air travel more easily out from the bottom of the laptop. Some of us like to work from bed, which is actually a bad idea. Bed cover is usually made from wool and cotton base material, which caused the heated air to be trapped under the laptop and cause serious overheating.
