There is a lot of good points about the device:

  • high performance
  • high resolution
  • tiny display borders
  • bright display colors
  • keyboard backlight
  • chasis materials
  • ~4h batery life (84Wh)

And some points that is not that good

  • glance display reflect light
  • touch screen cause fingerprints on display
  • tiny borders on touchscreen cause touches when change display angle
  • low HiDPI suport in Windows environment
  • lack of Ethernet port
  • Unavailability of dock accessories on Ukrainian market
  • Windows 10 HOME (that is not support virtualisation and bitlocker)
  • Long boot (15 seconds of BIOS POST)

Also there are McAfee Antivirus and additional DropBox space as a bonux for 1 year.

HiDPI compatibility

Windows, Windows applications, Java applications, sites, etc need may or may not be HiDPI aware. The issue with browsers is just about images that may (and one day will) be better for high resolution clients. The issue with OS and application are more painful. A lot of application just not usefull anymore on 15″ 4K display. OS trying too zoom Windows application to work with high DPI. For some it works, for some not.

Intel NUC D54250WYK

Introduction

Most annoying issue about my old PC was that it cannot playback 1080/60p and 4K video smoothly. Since 3D was not in use last couple of years I decide to switch from discrete graphics to internal. Also after some market investigation I decide to switch from classic desktops to nettop. So I was trying to buy nettop that will give me at least same computing power as previous PC but also gives me 4K and 1080/60p video playback. I chose Intel NUC Kit D54250WYK.

Also did some tests to compare with previous PC. Results in short: about same FPS in 3D, faster video playback (compressed 4K is OK), faster load, 90 times smaller (in volume), 20 times lighter, 10 times less power consumption, less noise. Details below:
