...and it rocks. Seriously. I've got Arch Linux loaded on this thing and it screams. The keyboard kicks ass. The trackpad is easily the best I've ever seen on a PC laptop. Picked mine up for a reasonable price with a 10% off coupon (I5, 8 gigs, 128 gig SSD which I upgraded to 512 gig on my own later in an effort to avoid the extortion like upgrade prices Lenovo charges on their site) for around $1100. I'm getting between about six and eight hours of battery life in Linux at the moment.
It's a sweet piece of hardware. Superfish? Who gives a fuck? I didn't even boot the M.2 SSD the thing came with. I immediately opened up the laptop and changed out the SSD as my first order of business. Buying a laptop this nice just to run Windows 8.x probably just means you are some kind of moron. Do yourselves a favor and move onto a better operating system.
Still while it is a great Linux laptop - it's not perfect - yet. The Trackpoint buttons dont work quite right in Linux yet but numerous patches (libinput, xorg synaptics driver and the kernel) are making their way into source trees everywhere. So for now it's a trackpad only experience as the trackpoint is useless without working hardware buttons.
In any event I couldn't be more pleased with this purchase.
