This was originally a long, somewhat positive review, but too many problems caused a short rewrite.
Jeremy Mossa
UPDATE: This computer started shutting down randomly less than two months after I bought it and won't take a charge so it died completely when the battery ran out.
Neil Flynn
I disabled zoom functions because I kept accidentally zooming, but left on two- and three-finger scrolling, which work fine.

Too many problems: screen malfunction, charger shorted, and a weak signal from the wireless chip. Avoid.

In a nutshell: the keyboard just sucks. It's horrible, terrible. I can't emphasize enough..if you are normally a fast typist, like I am, then this keyboard will make you mad. It doesn't register keypresses! WTH!

That said, everything else about this little machine is amazing. Screen is beautiful, it's fast, it boots in like 6 seconds! Strangers at the airport (I live at airports) flip when they see this machine.

Still, I'm considering returning it. The keyboard on any machine of mine MUST be an extension of my fingers...

You want a computer that is powerful enough to do real work. You also want something that has great battery life and is really portable. Oh yeah, you want it to look nice too. This machine is terrific and feels rock solid. It also has nice finishes like matching sleeve and case for the included wired ethernet and VGA video out dongles.

- Super fast power-on, wake, and shut-down/sleep -> no waiting around for the machine to be ready to do work
- The trackpad is silky smooth and very responsive and right clicking is done by pressind down the bottom right corner of the track pad
- Very light but rock solid
- Brushed metal looks very sleek and feels great

- Two finger scrolling is a bit jerky at times
- Takes a bit of practice to learn how to open the clamshell case

After reading a lot of reviews about the "flawed" keyboard and trackpad on this laptop, I was hesitant to buy it.
I'm a college student; I was looking for something super-portable to take to grad school, but more powerful than a netbook so I could process data. I admit, I went for the zenbook because, let's face it, it's just so darn cute!

After three months, I'm thrilled with this laptop.

The trackpad works fine. I disabled zoom functions because I kept accidentally zooming, but left on two- and three-finger scrolling, which work fine.
The touchpad will occasionally throw a temper tantrum and start behaving erratically. This happens about once a month, and all it takes to fix is a reboot, which takes about fifteen seconds. It usually happens after I have been using the computer for about a week without a real shut-down(and continuously postponing my update installs).

The keyboard is also fine once you get used to it.
It only took me a couple hours to stop missing keys; you do have to press them with a little more conviction than you do on other laptops, but it doesn't take long to learn.
That said, I'm a petite lady with tiny hands; I find the keyboard comfortable. If you've got bigger hands you might have more trouble.

I like the screen size, too, but my roommates complain that it is too small to watch a movie in a group. Solution: watch the movie on my roommate's laptop. Problem solved.

It is tiny but not fragile. The case that comes with it is attractive and means I don't worry about shoving it in my backpack and running off to class. I also love being able to pick it up with one hand and no effort.

The internet connectivity is great (some other reviews had mentioned bad wireless cards.

UPDATE: Amazon stepped up to the plate and took the product back with a full refund. They were under NO obligation to do so under the terms of purchase and I had originally contacted them just asking for help getting a response from ASUS. No back and forth. Just a very polit e-mail with a return shipping label. This was well and above what was hoping for. So two takeaways 1). DON'T buy a notebook with proprietary parts - especially from ASUS. 2). DO buy from Amazon. Great end to what had been looking like a bad story.
SSD hard drive failed after only a month or two of use (see description below). I start to look into replacing it and discover that the UX21 has a totally proprietary drive size/shape/format and you CANNOT BUY A REPLACEMENT DRIVE AT RETAIL. So if you decide to buy one of these, you are totally at the mercy of ASUS if your hard drive goes bad (as SSD drives often do).

That would also be OK if ASUS was willing to replace it themselves, sell you a replacement drive, or even answer their e-mail. I have been waiting for two weeks now and can't get a peep out of Asus (the only communication from them so far is a "customer service survey" which is ironic given I have received no service so far).

The customer service problems and the early drive failure might just be my bad luck, but I would have NEVER bought this machine if I had known that I could not swap out a part as prone to failure as a SSD hard drive. Do yourself a favor and avoid this sort of risk.

PROBLEM: The hard drive on this machine is failing. Getting "blue screen of death" in Windows. I also run Ubuntu Linux and getting intermittent shut-downs with "I/O error at sector XXXX" reported as the system fails. Most recently the PC has started to boot up into the BIOS screen and not recognized the internal hard drive as a boot option. My best guess is the SSD drive has failed (after only a month or two of use).
