ASUS Zenbook (UX21) Review
by Anand Lal Shimpi on October 22, 2011 8:00 PM ESTBattery Life
With limited time to test before I board a plane to Nokia World in London I only had time to run through one of our standard PC battery life scripts. I chose the web browsing test which involves frequent opening/closing of web pages until the battery runs out. It's a pretty stressful test that's not just indicative of web browsing but also battery life in general.
As you may have already seen from our UX21 teaser earlier this week, performance here is as expected. The UX21 has a 35Wh integrated (technically non-removable) battery, which just isn't a whole lot of capacity—particularly compared to your more run of the mill 13- and 14-inch notebooks. Battery life is naturally the price you pay for portability and form factor. You're looking at around 4.5 hours of continuous usage on a single charge. Obviously run something more CPU intensive and that number will drop considerably.

what if i work in a corporative enterprise (90% windows) ? do i have to switch to osx, wich i dont like, coss its not for working?btw im a unix sysadmin
and still prefer windows for workstations.. ALL THE WAY...
the real question is, why would i go with a portable that has a different os than my workstation?
you dont have to hate apple to like this thing...

It seems the vast majority of folks responding have a hard-on for apple and believe they are superior because of it. Jobs certainly did, the arrogant bastard. Some of us are still tech enthusiasts and still prefer using Windows and the freedom it affords. This site has become apple-centric, no doubt.lukarak - Sunday, October 23, 2011 - link
Is Apple forcing you to use their OS?pdjblum - Monday, October 24, 2011 - link
How twisted are you man? This is a review of a windows laptop. How has it turned into a discussion by a bunch of apple fanboys about how great macs are? No one is forcing you to be a total dick.jconan - Sunday, October 23, 2011 - link
But then you would have to partition the drive and give away that precious space to Win7 and 64gigs the bare minimum on a MBA is a bit already stranded.Shadowmaster625 - Sunday, October 23, 2011 - link
I dont understand why so much memory is used in standby. Why not swap most out and then have one single low power DRAM chip powered up to store the ~256MB~512MB that cant be swapped out? Then you can sleep a long time and still have fast resume.pdjblum - Sunday, October 23, 2011 - link
Some of us who frequent AnandTech still prefer windows. Obviously Anand prefers apple and so do many, if not most, of his readers, or at least his more vocal ones. Comparing a windows machine to an apple machine is like comparing apples to oranges. Apple's control over hardware and software makes it much easier to insure things work just right; however that control is limiting as far as windows users are concerned.Of course, many of your apple users will react badly to my sentiment, which is odd since I don't see how I could have offended. You, and your readers, can make out of that sort of reaction what you will, but why be defensive if you have such a great thing, which I am sure it is, at least to you, and your readers.

It will not be a bad reaction. However, buying a mac is not limiting, as you are free to use any operating system you wish. Buying any other pc is, because you are generally left without OSX.I have been using windows my whole life. And i still use them every day. But they run inside VMs on my Macs and other PCs i have 'equipped' with Mac OS X.

Not pcs fault that OSX can't run.lukarak - Sunday, October 23, 2011 - link
So? It's a fact, i don't care whose fault it is. It is not even a subject of fault. The clear fact is that with a mac i'm not limited in OS selection, either through VMs or 'native', and with a PC i am. So how is buying a mac limiting?
