Netbooks can be termed as ultra-portable laptop computers, as they are lighter and smaller in size than regular laptops. However, in spite of their size, they have almost the same features as that of a laptop, but at a very affordable price point, which makes them a very attractive proposition. Their main drawbacks remain that they are a little underpowered as compared to normal laptops, and also the fact that they don't come with an optical drive. However, with enough USB ports available, you don't have to worry about data transfer. However, when it comes to buying a netbook for a child, there are a few things that one must consider. First and foremost comes Internet security. Make sure that the operating system has parental controls, so that you can monitor and limit the websites which the child can access. Durability is also an important factor to consider. The netbook must be able to withstand anything from serious play to temper tantrums; hence, make sure it is tough, and can sustain such rugged use. Some netbooks have a 7- to 8-inch screen, while some even have 12-inch screens. Smaller screens improve the portability factor, whereas, larger screens enhance the multimedia experience. Last comes the price. Some of the best-selling netbooks in the market are available for around USD 300, and have all the basic configuration required for day-to-day use. Make sure you check out the device and weigh its pros and cons, before buying it. Also, prices will vary at different locations, shopping websites, and as per offers available. So confirm the same before making a final decision.
