Samsung NP900X4C ?
I'm a huge thinkpad guy I used a thinkpad t420s on the road. i5 2520, 14.1 1600 x 900 resolution, 16gb ram. Can hold 3 hard drives msata, main bay and one in the ultrabay. Or my config msata SSD, 500gb rotational drive and a dvd write. Battery life is only 4 hours or you can put in a 2nd battery in the ultrabay. Lots of options and lenovo international warranty is the best, it's actually ibm that handles it and you get next day service. It's under 4llbs. The screen quality can be iffy. Luck of the draw there.
Been using the samsung np900x4c more often. It's actually a big 15" screen in a 14" laptop body. Super thin, 1600x900, ivy bridge stays really cool, battery is over 8 hours, can handle 16gb of ram for an ultrabook that's really good as you can run vms or photoshop etc. Like 3.75 lbs. Never had experience with samsung warranty so I don't know how they are in that department.
