The battery lasts at economical working operation (Office, Internet only when it is needed) about 3 hours, regardless of how fast operation (WLAN permanently on, sometimes movies look) for two hours and in streaming or gaming, you can only talk of bridging, but that's ok.
Preinstalled Windows 8 is what I personally will not do much, since the present version of Vaios has no touchscreen and the learned App or tile appearance of the desktop so that actually lapsed. But you can also turn on the regular Windows desktop. More I do not want to say Windows, intuitively done differently, but the notebook can not.
The Vaio makes a steady, but not robust. In particular, the drawer for Blu-Ray / DVD appears me very rickety. The keyboard is its format to a desktop PC, so it has a number pad on he right side. Derr pressure point is agreeable, working with it. More than just getting used to (I work for a year now so) however the touchpad. While that is aligned centrally to the letter block, seen over the entire width of the notebook but much too far to the left. Since it has no physically recognizable Mouse Keys, you are caught from time to time the right button rather than the left. The touchpad can be well off without any problems.
Installation via blue-tooth runs smoothly, NFC I have not tested.
WiFi is running smoothly, but woe with me to 99%, it does not work again. The troubleshooting of Vaios appears to be based on the basic assumption: An I can not lie. This is annoying, but if you ignore the Council to restart the router and instead apply it to the laptop, it runs again.
Streaming, Blu-Ray and normal games (Age of Empires 3, Resident Evil 4) running clean and smooth. Whether the player can play Blu-Rays with invalid region code, I did not try.
Overall, a solid and reliable notebook with a few minor weaknesses. Especially if you want to actually use it as a notebook (ie the road a lot), I would probably still something View More stable. For me it's just a complete replacement for a desktop PC. Anyway, after installing a Blue-Tooth Mouse.
