This is a significant product, and a long-awaited one. Previously, if you wanted to have a notebook like MacBook Air, you'd be forced to switch to Mac regardless of how much of a Windows person you were. Nothing else on the Windows side was really even remotely comparable. Now, this is the first real alternative in the Windows camp.

Is it better than the MacBook Air? It depends. If you are a Windows person, it is. Previously, you had to be seriously biased to say any Windows-based laptop in the ultracompact category is better than the MacBook Air. Now, that can be an honest assertion. But if you are a Mac person, you might still say the MacBook air is better, which could be a debatable assertion, but a respectable one.

To me, ZenBook is better than the MacBook air, even if I objectively lay aside the operating system difference, because for my personal preferences I give a higher value to some of the strong points of Zenbook, especially its thermal performance. Your preference may be different.


(1) COMPUTING PERFORMANCE - First of all, in terms of the primary computing performance, including the CPU and memory performance, they're very similar, and both are very good. Asus' own tests say that the Zenbook is faster, but I don't feel much of it. This is, however, mainly because both are so fast. Comparing the speed of the CPU and memory of these two computers really has very little practical meaning. Only labs would be interested in doing that. Who is going to choose a computer over another because one opens up Microsoft Word in 1.5 seconds versus the other's 1.7 seconds? You see what I mean.

ZenBook does have much faster data transfer through its USB 3 port.

Summary: The Zenbook is exactly what I had in mind when I needed a lightweight, low maintenance portable to carry on business trips with me. Tablets or netbooks were not an option because of their limited capabilities and inadequate performance.

The Zenbook is very pleasant to look at and different, but not difficult to use- in fact, my experience has been enjoyable. I've not experienced any problems described by other reviewers. Perhaps Asus is listening and my machine is a reflection of that.

I was surprised at the negative comments on engineering design, choice of components, etc. The emphasis on the keyboard and touchpad are understandable in that they are different - the manual explains how to use the keypad and what to expect. I've had electrical "pops" on many laptop chargers, and this one did so about 5% of the time. Asus provides a solid warranty on its laptops. And, I have dealt with their support organization before on warranty work and service calls, with positive results, except one, where it took time for them to find a replacement laptop - the outcome was satisfactory.


1. The Elan touchpad works very well and has a sensitivity region that shrinks in size when you are typing on the keyboard so that you don't accidentally activate the touchpad while typing.
2. While a source of complaints, the keyboard and keys definitely enhance the look. Keys provide positive feedback with a "tactile click" created by the key giving way when it is pressed down far enough. It's also reliable - key presses that failed were not the computer's fault.
3. When done working, I just close the lid on the machine to suspend my work - (it has "sleep" rather than "shutdown" as the default option to power off your computer).

I bought this beautiful ultrabook at Frys last week and kept it for 5 days. I actually bought it right off the back of the truck that had just arrived. I was truly excited to get this machine(BUT): The keyboard is truly bad. The trackpad started off bad until I realized I needed to run an update from Asus to get all the drivers updated. The trackpad improved greatly with the updated driver, yet is still FAR lacking compared to a MacBook trackpad I do not know why).

Back to the keyboard. No driver can fix this keyboard. The keys are flat on top. The keys sit very close to the surrounding material underneath. You can push a key at the corner and touch the underlying material and not register a key push. I cannot replicate this on any other keyboard I have in the house. This means you bottom out the key before it registers the key push. Bottom line: you miss every fifth letter unless you hit the key right in the middle. I like to keep my job and I need to spell correctly. Therefore:

I took this machine right on back to Frys. The machine is truly beautiful (prettier than the MacBook Air). The sound from the speakers is very nice and it is much quieter than the MacBook Air (which we also own) because the implementation of the internal fan is much better on this Asus machine. The screen is nice too.

The keyboard sucks though and the trackpad is merely passable. I hated to take it back, but how Asus turned this into the Anus with a keyboard that doesn't work is beyond me. What screwed up committee let this happen?
