Inspiring possibilities

Boasting an innovative 360-degree hinge, the Dell Inspiron 15 bends over backwards to please with four different modes: tent, stand, laptop, and tablet. Its 15.6-inch Full HD wide-angle display features more screen and less bezel, so you have plenty of room to spread out—be it work or entertainment or both. The 7th Gen Intel Core i7 processor keeps things humming smoothly no matter what you throw at it. And the massive 1TB hard drive means you have loads of space for all your digital stuff.
