We generally liked HP's redesigned Spectre x360, but it had a few flaws: It dropped some particularly useful ports, and there was no 15-inch model for people who need more screen real estate. Consider those issues solved. HP has unveiled a 15.6-inch edition of the new Spectre x360, and it's a lot more than just an upsized version of a familiar 2-in-1 PC. To start, you're getting much nicer visuals. The larger Spectre ships with a 4K IPS-based touchscreen and dedicated graphics (albeit an older GeForce 940MX chip), both of which are miles ahead of the 1080p display and integrated video on the 13-inch system. However, it's the subtler additions that you might appreciate the most.
