The design is pretty cool and the keyboard is very comfortable.
As for the battery life, I did not test it yet but I'm sure it has a good 6-9 hours with correct settings.

Asus's strategy seems to be stonewalling the customer until they give up.

Have only had this laptop for a week but it is awesome. Love the ability to switch between NVidia performance GPU when I have it plugged in and then be able to switch to the 2D Intel mode on battery. The second day I had this laptop I used it for a full 10hours for classes and homework before needing to charge it, and it was still only at 15%. I loved being able to the first weekend throw it into performance mode and play games in high quality graphics mode.

I came from previously owning a 15.6" HP dv6700z laptop. This is a huge improvement at a mid-line price. I love the way the LED screen just pops color at my compared to the old screen. I am now able to go to classes and use my laptop without hunting for plugs and the size is perfect for a mobile laptop that still feels big enough that you aren't leaning in to look at the screen.

I find that the dual core i3 with hyperthreading is perfect even when it is under-clocked on the battery mode.

No gripes yet but will update as my experience with the product grows.

Overall, this is a very good value for the price you pay and what you get. Stat wise the power from the i3 CPU and the nvidia 415M gives you more than enough for general email use, video viewing, gaming, etc. which is what I use this laptop for. It runs Steam with no problems, it also runs league of legends at 60fps with no problems (very smooth).

the stated battery life is of course an exaggeration. there is no way you have 10hours of actual usage. you can count on anywhere from 3-4hrs to 4-5hrs, depending on what you are doing at the time. there are 4 power settings on the laptop, high performance, entertainment, quiet office, and battery saving. these settings have been pre-configured to limit the CPU's max and min processing power, screen brightness, etc. I only use high performance and quiet office. the battery saving mode requires a soft reboot of the systems (almost like hibernation) to kick in, and once in battery saving mode, the laptop will turn its screen off every 2-3 mins if you don't move the cursor (even during video viewing). So battery saving becomes more of a nuisance than anything else.

the biggest downside to me personally would have to be its AC adapter. this thing is bigger than my dell ac adapter, and the cords are too long and too thick and the band they give you is not good enough for you to pack the cable and adapter together effectively. but this is more of a pet peeve than anything else, might not bother other people.

*side note, it says it has a backlit keyboard, as far as I know, it DOES NOT have a backlit keyboard

I needed a new laptop and my husband did a tremendous amount of research before we settled on this ASUS. We were looking to balance speed, weight and price. This one is perfect. It is lightning fast, the keyboard is very comfortable, and I can easily tote it anywhere I need to. It does not have an internal drive, which suits me fine since I usually only use the CD/DVD drive a few times a year. And the drive would have added a lot of unneccessary weight. We purchased an external DVD drive that plugs in easily to the USB port. This is our second ASUS computer (our teenage son has a refurbished one at college) and we are very pleased with the quality for the price. Outstanding laptop!

I have this laptop for only 4 days, after 3 month of reading alot of reviews. my favorite computer was the hp-dm1 and I still recommend it to everyone that want small computer with good performance and also good features. I decided to go for this one because I couldn't buy the hp from there website and from amazon I preferred to add like 120$ to get this asus u31jg with better cpu and good graphic card.
I already explored it in 4 day, to give you this review.
this is my first laptop so I cant compare this to others.
this is a notebook with 13.3 inch screen, just the right size for a portable notebook and not too small.
I must start with the built quality:
my notebook as a defect in the frame of the screen, the frame in the lower screen area is disconnected from the screen, and that could cause some problems in the future, in overall the built quality is not so good and i give it a score of 5/10.

this is fast laptop with the fastest i3 cpu of intel. also the laptop come with nvidia 415m GPU and the optimus technology that works very well most of the time.It has hdmi port and I was surprised to see that it run 1080p very smoothly and also runs smoothly civilization 5 on 1080p with medium settings.
score: 9/10

great battery with alot of time using without need of charging. for regular use of internet and stuff this battery lasts about 5-6 hours in average. with gaming and so this will lasts like 3 hours or more.
the downside is the ac adapter that is very big and very heavy, which reduce the benefit of this light laptop.
score: 9/10

keyboard and touchpad:
in overall, this is a good keyboard with a little bit flex and some minor problems.
the touchpad is worse than the keyboard.
