Engadget - With back-to-school season upon us and Intel's Haswell launch just around the corner, now's a great time for PC makers to start unveiling their summer lineups. Two weeks ago we heard from Sony and today it's HP's turn: the company just refreshed everything from its mainstream notebooks to its high-performance machines. Heck, even the pint-sized dm1 got a makeover. With the exception of that machine (now called the Pavilion TouchSmart Notebook), everything here will be offered with Haswell. There's a little something for everybody, and it's all waiting for you in a neat summary after the break. Join us as we break it down.
