I have recently bought a Y580 and would like to share some of my views on this machine. Since there are different models available in diffrent places, I'd better list out the core specs of my Y580:

Processor: Intel i7-3610QM
RAM: 4GB DDR3 1600MHz (free upgrade to 8GB)
Hard disk: 1TB 5400rpm
Display: 1080p 15.6'' FHD LED Glare (1920x1080)
GPU: Nvidia GTX 660m (2Gb GDDR5)
Optical drive: Bluray Rambo (Burn bluray disk)

1) Build quality
The machines has excellent build quality. The top cover is made of metal which gives a "high-class" feeling to the laptop. The palm rest and its surroundings, as mentioned by anther review, are made of a mixture or plastic and metal, which is unlikely to get dirty easily. The overall construction of the machine is firm and solid.

2) Display
The FHD display is simply gorgeous. It gives sharp images and vivid colours while having no signs of over-saturation. Reading on it is definitely comfortable and enjoyable. I would definitely recommend the upgrade to FHD screen,which allows enhanced experience when watching movies or playing games. The screen is glossy, but the reflection is okay for me.

3)Keyboard
The Y580 has a island-style chiclet backlit keyboard. The slightly curved button design is user-friendly. The physical feedback when pressing the keyboard is great as there is no flex at all and the re-bounce is great. I would say that the keyboard is as great as the MacBook Pro, especially with the backlit feature. Working in a completely dark environment is not a problem, although the intensity of the backlighting cannot be adjusted. Also, the position of the "Shift" key on the right hand side is a bit strange. I need time to adapt to it.

4) Sound/ Audio
The Y580 features JBL speakers and indeed they are impressive. The sound quality they deliver is the best I've ever heard. The sound is solid and focused even at max. volume.

5) Performance
This laptop is like a beast. With the latest i7 ivy bridge processor, it is able to accomplish every task quickly and efficiently. With the GTX 660m, most of the games can be handled quite well under 1080p at high settings. Obviously the fans turn faster under heavy load and more hot air is produced, but the machine shows no signs of over-heating. The palm rest as well as the keyboard is still very comfortable to use.

6) Storage
This is probably the only weakness of the Y580. 1TB of storage is pretty adequate, but the speed of transferring files is relatively slow under 5400rpm. Anyway, this is not a big problem for me. For those who cares about this, an upgrade to SSD can be done by yourself.

7) Conclusion
Before I bought the Y580 I had been actively looking for a capable laptop. Clevo is my first choice because of the monster specs and reasonable price. However, there are no Clevo resellers in HK amd warranty is an issue, so I didn't pull the trigger on that. Finally I decided to get the Y580, which is also in the similar price range and equiped with similar components. Now I find out that the Y580 is actually as good as the other "gaming laptops" manufactured by Clevo, Asus or MSI. For those who have ordered a Y580, you have definitely made a good decision. For those who are consiering, I would definitely recommend it =)
