The HP OmniBook 3 16 has good battery life and strong multi-core CPU performance in a light 16-inch chassis, but its design is a snooze and it's not great for 3D graphics. At risk of dating myself, I'll admit the word "omni" always reminds me of a particular nerdy reference: the OmniMech from the Mechwarrior PC games. Versatile yet all-around great, OmniMechs ruled the game's virtual battlefield. That sets a high mark for HP's 16-inch OmniBook 3 to hurdle, and while the laptop does have strengths, it also suffers from weaknesses that don't seem very "omni" to me.
