Engadget - You've seen that laptop before. You know you have. Stumped? Okay, here it is. HP just announced the 11.6-inch 3115m for the business market and it is, for all intents and purposes, a rebadged Pavilion dm1z being marketed to a more buttoned-up kind of customer. For starters, it looks just like the newly redesigned dm1, flush trackpad and all. A dual-core AMD E-450 APU, 1366 x 768 display, Beats Audio and battery rated for 11.5 hours come standard.
