I'm currently using this laptop, and it is phenomenal!
I paid the 1k through Bestbuy as a Christmas gift, and it hasn't failed me yet. The screen is amazing, especially in that you can still visibly features on the screen from a far away angle since most laptop screens have a glare/reflection at side angle (not sure how that helps in a particular situation).
Keyboard has a great feel, love the backlight, and the number pad. I will say that number pad can be at times finicky with having to press the num lk on/off (even though it was on) for using it in some app; also I have a tendency to mis-hit the arrow keys since they're the same size as all the other keys, which would help if they were slightly larger to distinguish them (been training my fingers though).
It's very quiet when running at full speed and it doesn't heat up too bad (if your working on you lap for a long time, of course it'll heat).
All of the programs I use work great, especially when it comes to processing. I work with Labview and Matlab quite often and I'm very impressed with the computational speeds. If I do have problems with programs speeds/operations, I've found that it's mainly due to operating in Windows 8.1.
I'll be honest in that I don't use the touch screen that much unless its for zooming or games. I think a tablet would provide some greater functionality of the touchscreen. Actually, if this "laptop" had the ability to detach the screen into a tablet compatibility, it would be my dream machine and love it for 3 years.
In other aspects (not trying to repeat what other reviews have said), I do wish that the audio & mic jack were separated, but I guess that means I'll have to upgrade my headset. Also, you should probably disable the notifications for devices with that jack because you'll constantly get "a device has been plugged in" or "out", which to me, is just annoying for it to constantly to do so.
Biggest complaint is the touch pad. I really don't like the feel of it, and do wish that it separated the left and right pad with a button and just leave the rest of the area as mouse control. Also, wish that it had a blu-ray player drive since it has the capability of playing them.
