June 7, 2012 Update: As one person pointed out, Asus is about the release the Zen Prime, or the second generation of the Zen Book. The following review pertains ONLY to the first generation. Some of it may still apply (I'm pretty certain Asus will still include a bucket load of crap bloatware) but as I haven't seen one I feel it's important to note it so I don't confuse people.

Also, as part of this update I'd like to say that I still have the Zen Book and I still like it. I've found that the keyboard is a bit touchy but works MUCH better if you put the thing on a hard, flat surface like a desk. Typing in your lap you may miss more keys than typing on a table or desk. In the time since this review first showed up, I've managed to put a couple of scratches in the spun aluminum lid of the machine as well. Obviously scratches make no real impact but they certainly do stand out. Everything else... pretty much still awesome!

Oh yeah, you can see the screen outside on a sunny day!

And now, back to my regularly scheduled (and unedited) review:

By now there are quite a few people reviewing these machines and there are some common themes. But before I get into it, for those that haven't really paid attention there are a number of models and you may wonder "Does THIS review for this model really apply to the one I'm looking at?"

The short answer is pretty much yes. There are really only a few variations and the biggest is how big the screen is. There's an 11 inch and a 13 inch. The other two variables are which processor you have and which hard drive you have. That's it. So for the most part a review for one model of Zenbook applies fairly well to all other models.

So, the common themes you may have seen in order:

Color: Silver Aluminum
I have purchased a UX31E and UX21E for my office with high hopes. If they were good enough, I was going to purchase several more for my staff. I very much wanted to like these ultrabooks. They look nice, the shell has a very solid feel and they were very light (which was very important to me, since I am usually out of my office a lot). The screen is very crisp and bright. I love the fast start-up times from boot and hibernate. I have read many reviews talking about how bad the touchpads were, but I figured it would eventually be fixed with driver updates, so I purchased these laptops anyway. There are two types of touchpads out their for these ultrabooks. Luckily both of the ones I ordered came with Elantech, which everyone seems to say is the better of the two. The first thing I did was go to Asus's web site and download the latest drivers. I had no problems with the touchpad or network connectivity that some have reported - but that is probably because I updated the drivers first thing, which is supposed to solve those problems.

The performance of both machines were better than I expected, but I will say the UX21E had the faster hard drive. It came with 128GB SSD and after running some benchmarks, it showed it was much faster than the 256GB SSD in the UX31E. They probably were made by different manufactures, but I did not try to verify that. Battery life wasn't as good as I hoped, but certainly seemed to do a respectable 4-6 hours under constant use and much longer on standby. The variance in how long the battery lasted just dependied on how much of a workload I put on it. For instance, if I was just checking email and editing Office, Powerpoint & Excel files, then it would be closer to 6. But if used it for more intense workloads, then it would last closer to 4 hours.

I won't harp on the appearance of the materials, font's used, etc. Yes the weight may be different then Asus has advertised, there are alot of variants of the machines in each form factor (ux21 or ux31) and this may explain the discrepancy in the specs. Either way the design is impressive and it is a stunning notebook.

Other reviewers have been accurate regarding the poor performance of the atheros 9485 wireless card. I have had a similar experience with my unit running it in it's unboxed condition.

I flashed the BIOS from 204 to 206 (using winflash), updated drivers for the sentellic track-pad, the atheros 9485 WiFi, bluetooth, and etc, removed alot of Asus bloatware, specifically "Power4Gear" & "LiveUpdate".

Now this thing is starting to impress me. Network card is running as fast as the netgear card on my PC. Track-pad is working as it's designed (although I'll admit it takes some practice to get accustomed to it).

It's hard to believe that people overreacted and sent them back before even updating the software. Do realize that you are what's considered an "early adopter" if you purchase the first machines off of the production line. If you don't realize this then you are unworthy of this machine, go get an apple.

I read a lot of reviews of other models of this laptop while I was waiting for it to arrive in the mail and I began to worry that I had just spent a lot of money on something that was released prematurely and had a lot of design flaws. Let me just say that from my experience this has turned out to be not true. Like any new laptop you have to set it up to work best for you. If you don't want to spend the few seconds customizing it to your tastes then get a Mac. Apple works great out of the box but offers the user little in the way of customization.

1) The keyboard is fine. The keys are not misaligned. Although it does take about 10 minutes of getting used to a different layout, this is no different than any other new laptop. Laptop keyboards vary due to size differences. That is all. They keyboard is nice, comfortable and works well.

2)Bad internet connection: not true. If you are running off the battery the laptop goes into a power saving mode. However, you have the option of putting it back into high performance mode. The power saving mode is fine for word processing but if you want to use the internet and get your normal performance you need to switch it to high performance mode (Fn+Space). And even if you do run it in high performance mode while unplugged you still get 4 or 5 hours out of the battery, which is pretty amazing.

3) Track-pad issues: Better than the one I had on my Dell. Update the drivers and it is fine. In fact, I didn't even update the drivers for about 2 days and it was still fine. The one initial problem I had was that when I tried to scroll up or down (a two-finger swipe gesture) sometimes I would inadvertently zoom in or out on the page. This was corrected by a simple settings adjustment.
