Just to clarify some things here: They are vents, they are moving from Y series to U series processors for the G2 hence the introduction of fans (on a side note Intel's naming conventions for the Kaby Lake CPUs is somewhat confusing but bless their souls). Speakers have been moved to front facing, has to do with the tablet being Skype for Business Certified along with the collaboration keys you'd find on the Elitebook Folio G1. They have improved the fingerprint scanner, it's capacitive now - also offering an IR camera for Windows Hello. Screen is bigger at 12.3", resolution has been bumped to 2736 x 1824 (matching the Surface Pro 4). The hinge reclines back further, gives you a more flat and comfortable inking surface. Fancy new HP logo, of course.
