HP's new Pavilion PCs include a 15-inch hybrid laptop

The largest-ever x360 is the highlight of HP's new computer lineup.

Spring is well underway, and that can only mean one thing for HP: time to unveil a wave of new home PCs. The company has trotted out a host of new Pavilion PCs that pack both obligatory upgrades -- thinner, faster and new colors -- as well as a few welcome improvements. The highlight by far is the Pavilion x360 line of convertible laptops, which gets a larger 15.6-inch model (above) on top of the existing 11.6- and 13.3-inch versions. Yes, HP's most affordable hybrid is now big enough to replace larger portables. You'll also find slimmer designs for the two smaller versions, optional keyboard backlights on the two larger systems and your pick of current Intel chips ranging from a Celeron to a Core i7. When the Pavilion x360 updates arrive from May 15th through May 29th, prices will start at a frugal $380 for the 11.6-inch PC, $480 for a 13.3-inch version and a not-too-shabby $580 for the 15.6-inch model.

There's more to the refresh than that, of course. The more conventional Pavilion line is slimming down at the 14- and 15.6-inch sizes, and the larger systems (including the 17.3-incher) can carry the latest Intel Core i7 or AMD A12 processors, up to 16GB of RAM and storage that can include both a 128GB SSD and a 2TB hard drive. Systems start showing up as soon as May 18th, with prices starting at $540 for a 14-incher, $580 for the 15.6-inch Pavilion and $900 for the 17.3-inch behemoth.

On the desktop side of things? Some Pavilion All-in-Ones now carry a "micro edge" display that cuts the border thickness by 75 percent, and there's an optional RealSense camera for both gesture commands and signing in with face detection. A new Pavilion Desktop, meanwhile, is 30 percent smaller than its ancestor while sporting up to a Core i7 or AMD A12, 16GB of RAM, 3TB of storage and budget GeForce GTX 750i or Radeon R7 graphics. The all-in-ones first show up between July 3rd and July 10th with prices starting at $700 for a 23.8-inch display and $1,000 for 27 inches. The Pavillion Desktop hits on June 26th for $450, and it'll be joined at the same time by a 32-inch quad HD Pavilion Display that sells for $400.
