Thin appears to be in, with Dell joining the recently refreshed Lenovo X1 laptop for a slice of something slender.

Instead of a business-grade 13 incher, Dell’s serving up the refreshed 15 inch XPS model, upgraded with a choice of either Intel Core i5 or i7 processors, NVidia GeForce GT525M graphics, two USB 3.0 ports, eSATA, HDMI, Gigabit Ethernet, 1.3 megapixel webcam with HD video, DVD slot-load burner, Bluetooth 3.0, and 802.11a/g/n WiFi.

There’s also a Full HD 1080p 15.4 inch screen here, something that we rarely see on laptops. Most 15 inch notebooks only manage a 1366×768 screen resolution, something that’s just barely above 720p HD and what you’d expect to find on a 10 to 13 inch laptop.

The new spec’d up XPS 15z manages to fit all of this technology into just under 25mm, with an aluminium and magnesium-alloy case keeping everything safe.

Dell said to us that the XPS 15z will be “the first in a series of upcoming thin Inspiron- and XPS-branded products that deliver the ultimate blend of style and performance,” so take that as you will.

From the first glance, we’re a little surprised as it looks like Dell has done what it can to product the most Apple-esque product we’ve seen in a while. The specs look to be on-par with what Apple refreshed its MacBook Pro line-up with recently, but for several hundred dollars less, with an RRP starting from $1399.
