Pros -Great Screen w/ good color spectrum (95% Adobe-rgb)
-Very light for the performance packed into it
-Love the brushed Aluminum
-Quiet keypad, but still comfortably firm
Cons -Can get scratched (Depends on how you use your laptop and where)
-5400rpm HD standard w/ 24gb i-SSD
-Finger print magnet on the outside shell
Summary All in all, I love this little ultrabook. The touchpad isn't perfect out of the box, but the new drivers helped a ton and fixed 90% of the issues I had with it so I'm very happy. Additionally, the bloatware is removable , but still a pain in the butt at first. The biggest thing that needs to change is the included HD. It should be a SSD standard, but instead its this weird hybrid. Works resonably enough, but budget into your purchase that upgrade as that will turn this ultrabook into a beast! And an 8gb 1600mhz stick wouldn't hurt if you can afford it. I really like the machine though. It's just a great little work tool!
Pros 1080p IPS display, good multitouch mouse-pad. Improved keyboard resistance. Price is just right for this kind of setup.
Cons non-replaceable SSD storage. There tend to be light bleed on all IPS display.
Summary I'm pretty happy with my UX31A Zenbook. The best Win7 Ultrabook screen you can get atm. Despite the light bleed, it's hardly noticeable until you watch something really dark or when Windows boot up screen. It's a really good update from last gen Zenbook because Asus has listen to most customer complaint and they address most of the issue on this new generation of Zenbook. I had a blast with the mouse-pad because it's very responsive so I don't know what Cnet is talking about why it suck. Keyboard is definitely better than last gen and less flex. The 1080p ISP display is beautiful. Viewing angle is better than most LCD display use in computer today. One thing I like Asus to change is to QC the IPS display before shipment because almost all of it has light bleed on them.
Pros Looks nice.
Cons Cheap, Chinese Garbage.
Did I mention that the parts are all cheap, Chinese garbage?
Summary In summary, the ASUS computers look nice, but all of their parts are cheap, Chinese crap that will not function properly after a short amount of time. For instance, I bought the computer in January and a couple months later, the disc drive was not reading the disc. I tried checking the drivers and it said it was working properly... apparently not if the disc is telling me there is no disc when clearly there is.
