With business executives living life out of a suitcase, carrying a bulky laptop for work has become a boring and difficult affair. Agreed, laptops (especially the high-end ones) offer a host of features and functionality that are incredibly useful. However, while commuting, large-sized laptops often cause inconvenience to the user. This is the reason why net books have become a rage these days. Net books are small, affordable, and highly portable laptops. Now, if you think that the functionality of a net book would not match up with that of a laptop, you are mistaken. Though a net book has less powerful processing power compared to that of a laptop, it is best suited for surfing the Internet, and general computing. Weighing less than 2.5 pounds, a net book consists of a 10-inch screen, 1GB RAM, and Intel Atom processor. The rising demand for net books has triggered the production of a variety of net books, under different brand names. What are the factors to be considered before buying a net book? The first thing that you should look into a net book is its processor. In general, Intel Atom processors are used in net books. The year 2010 witnessed the introduction of the Intel Atom N450 Processor with a speed of 1.66 GHz. Before the arrival of the Atom N450, processors like the Intel Atom N270 and Intel Atom N280 were used in net books. A net book should have a minimum 1GB RAM. This is important for smooth running of applications. Net books come with Linux or Windows operating system. Other factors to be looked for are battery life, screen size, optical drive and storage capacity. There are a number of broadband deals available in the market. If you want the GPS functionality on your net book, you should purchase a broadband plan that offers you high speed, and minimum downtimes.
