Asus Zenbook 14 or Vivobook S14. I'm using the 2nd one, S410UN to be exact. i5-8250u in me version (but I believe there are ones with an i7), 256GB SSD M.2 (upgradeable, theres also a free 2.5" bay in there so You can easily add 2nd drive, 8GB ram but only 4 is soldered to the mobo, other 4 is an SO-DIMM so You can easily upgrade that to be 12Gb or so total. 14" Full-HD matt display, pretty decent battery live, weigts about 1.4kg so about 3.1 lbs. Overall It can easily do in the office, and some light gaming as well. Works great for me so far, I dont think i'd change it for something other.
