Everyone has an laptop based on Intel's Ultrabook spec these days, and if they don't already, they showed it off at CES last week. Just being thin and light isn't enough to stand out in the crowd now, and HP knows that. To that end, they've produced the Folio 13, an Ultrabook that they're aiming at the business market. The 13-inch laptop still manages to come in at under a grand, so it's worth considering even if you don't spend most of your working hours between one terminal and another. How does the Folio 13 stack up to the rest of the Ultrabook competition? I spent the last week finding out.
