"Business travelers know that there are two essential factors that need to be considered whenever one is purchasing an ultraportable laptop. The first is that an ultraportable laptop should be small enough to carry around whenever one is traveling, and it should be light enough not to cause physical pain at the end of the day. The second consideration is functionality.
