It's yours and yours alone. You won't have to time share it, since your kids won't be interested in playing games on that small screen,
Most of the new ones are wireless enabled, meaning you can work at McDonald's and Starbucks, and many other public places.The Bad:
That small screen. It can make your eyes cross after eight straight hours of work. An ultra-small, ultra-light laptop may seem like a good option, but over the long haul it may not be the best choice.The Ugly:
Laptops are not. They need to "breathe" from the bottom, in order to cool themselves down. They can't do that sitting on your lap. Even if you have a high tolerance for extreme heat, and don't mind having your thighs singed, it is sure death for a laptop if you work that way for very long. A better choice is to use a small tray and make sure the computer is propped up a bit for maximum air circulation
Battery life is a lie. The time a laptop can be expected to work on battery is inversely proportional to the time you need it to work on battery.
Power cable connectors and connector pins are much more fragile than the laptop itself. They dangle, they twist, they cause the pin to loosen, or small wires to break. Try to remove some of the weight on the connectors by resting the top part of the cable on the table or tray next to the machine.
