If your work is mostly online and you have built a career in that, you cannot afford to get away from your computer. Some people prefer working on a desktop computer but if you are away, it would be good to invest in a laptop computer or a netbook so that you can check your email and perform some basic online functions wherever there is wifi internet access.
Netbooks are cheaper and much lighter to carry around. A lot of people trust the line of Samsung netbooks because of their quality. And of course, it is a trusted brand with good customer support, which is why it has gained massive acceptance among many mobile computer users.
