Why cheap netbooks it is favourable to buy?

Why cheap netbooks it is favourable to buy? Because at them the lowest price!!! You can buy good new netbook but only under the lowest price! I always considered that netbooks should cost cheaply and thus to allow to work comfortably on the Internet. Now new netbooks began to cost very cheaply, but now on them it is possible not only to sit easy on the Internet and as to play games, to look HD video and many other things. What for to pay more when it is possible to buy simply cheap netbook and to enjoy work!
