I have one that is now 2.5 years old. Specs-wise, it was basically top of the line. Quad Core i7, 16GB RAM, 500GB SSD, 3200x1800 touchscreen, GeForce 750m GPU (which was one of the best mobile GPUs back then). It has a lot of nice touches that lower end models don't have, like 2 or 3 USB3 ports, with 2 or 3 USB ports that have power even when the laptop is off (super handy for charging a phone on an airplane while your laptop is still in your bag, for example). Wireless N networking, HDMI and MiniDP connections, able to drive two external monitors at once along with the laptop screen (up to 1920x1200 over HDMI and 4k over miniDP). The touchpad is pretty decent. backlit chicklet keyboard with variable brightness. SD card slot, 1/4" headset port... the only thing it's missing is an ethernet port, but that's just because it's too thin for the port. A USB3 gigabit ethernet adapter is cheap and works great.
And it's pretty damn light for a 15" laptop. Easily one-handable (I think it's like 2 pounds IIRC).
And what's great is that you can crack it open and replace stuff - I swapped out the hard drive and replaced a malfunctioning battery myself with just a torx screw driver (super tiny torx, but still, no glue or special tools or anything).
It was pretty expensive - like $1900 IIRC. You're paying for the high res screen, better build quality, and thinness/lightness. But it's still like $500+ less than an equivalent macbook.
