I bought this laptop a week ago but now it is in service because of awful backlight bleeding. Laptop is amazing, screen is amazing but screen flexes a little and I think it is difficult to make flexible screen without backlight bleed. This might be its flaw. I hope I get it fixed... It is strange why they didn't replace it for me but sent to Asus certified service..
for a quick mini review:
FHD IPS matte screen looks really great, colors are very nice and you can use Asus color presets to change 'warmth' of the screen.
Sound system is astonishing, I don't understand why some people complain about it. Sounds are really deep and it feels like you are in cinema. Haven't ever used it at full sound, because even 50% is too much.
Keyboard is wonderful, I got used to it really quickly.
TouchPad is not that bad - I got used to tapping gestures and didnt have to use buttons. This way it is really pleasant experience.
I played GTA 4 on FHD and high graphics. I believe I could have gone on very high easily, but it was enough for me, as I'm not a graphics freak. Didn't notice any overheating problems, fans spinned quietly. I played for like 3 hours. Even AC-DC converter didn't heat up.
About the charger - it is really massive.
You can always hear fan spinning and HDD ticking. It is not very quiete. IMO opinion HDD has to be replaced as soon as possible because it is slowing down this machine considerably.
Can't really say anything about a battery, because havent used it on battery yet.
Build quality is very nice, except for the screen and DVD drive sticking out a bit.
The last thing is finger prints - backcover and top cover catch all of your fingerprints and it seems impossible to clean them :D But thats not a problem for me.
I had no problems with drivers, just simply installed everything from Asus disc and then updated video card driver.
Really great laptop - can't wait to getting it back. If you have any questions about it I suggest reading this thread:
