Lisa Gade reviews the mid-2015 Dell Inspiron 15 7000 15” laptop with a UHD 4K touch screen. Dell also offers a 2-in-1 that’s essentially the bigger version of the Inspiron 13 we recently reviewed, while this one is a conventional laptop with touch but no pen support. The 4.65 lb. Inspiron 15 has an aluminum casing and a sleek, premium design. It has a 4K display (it’s also available with a 1080p IPS touch screen), backlit keyboard, dual band Intel 7265 WiFi AC, Bluetooth 4.0 and a webcam. Unlike some other premium 15” models, it runs on lower power ULV 15 watt dual core Ultrabook CPUs, and it’s available with Intel HD 5500 graphics and optional dedicated AMD Radeon R7 M270 4GB DDR3 graphics.We look at the high end $1,449 configuration (7548) with the 2.4GHz 5th generation Intel Core i7-5500U CPU, switchable AMD graphics, 4K display, 16 gigs of RAM and a 256 gig SSD. The series price starts at $680 for a Core i5 and 1080p display. The base 4K model is $1,100.
