It was way back in 2011 that ASUS launched the Zenbook series. The original UX21E and UX31E were the first of the thin and light Ultrabooks from ASUS to bear the Zenbook brand, and featured an all-aluminum chassis. ASUS has kept the styling consistent over the years, and refined their Zenbook with each new model. The new UX305 is their thinnest and lightest incarnation to date and keeps the Zenbook aluminum frame, with the distinctive concentric-circle finish on the lid, and squeezes the laptop down to an incredible 12.3 mm thickness.

Part of that story is what is powering the UX305. Intel’s Core M processor is a 4.5 watt chip which has compressed the entire system on a chip into a much smaller package than the traditional Core processors that have powered the other Zenbooks. ASUS has created a system board with a ten-layer high-density PCB which is only 0.83 mm thick, and roughly the size of a six-inch smartphone. Core M, with its low Thermal Design Power (TDP), also enables fanless devices, and ASUS has done this to provide a laptop computing system with no moving parts at all, and therefore it is virtually silent.

The most amazing thing about the ASUS UX305 though is that the company has crafted an all-aluminum, thin, light, and capable Ultrabook for only $699. With this kind of price point, one would expect sacrifices to be made in the specifications, but that is not really the case at all. For the base starting price, the UX305 comes with the Core M-5Y10 processor which has a base clock of 800 Mhz and boost to 2 GHz, along with 8 GB of LPDDR3-1600, and a 256 GB Solid State Drive. The display is a 13.3 inch 1080p IPS panel, and in April a 3200x1800 model will be available which includes multi-touch.

For the US market, the $699 5Y10, 8GB, 256 GB 1080p model will be the base, however they will offer other configurations in other markets. As far as specifications, there is very little to complain about. ASUS has still managed to fit a 45 Wh battery onboard, and it has all of the ports one would expect of a modern Ultrabook, with three USB 3.0 ports including one port with sleep charging, a micro-HDMI port, a headset jack, and a micro SD card slot. They have even fitted a 720p webcam. Really the only spec that that might be considered cutting corners is the 802.11n wireless, but some models will come with 802.11ac as well. ASUS has packed all of this into just 1.2 kg, so the UX305 is very light too.

One look at the UX305 and you can instantly tell that ASUS is going for those who are after a premium Ultrabook, but with a budget price. However that budget does not mean that it skimps on the necessities like storage or RAM. At CES, I was hopeful that the push to lower cost devices with solid state storage would be right around the corner, and clearly that is the case. Many of us who follow technology get asked for recommendations on devices to purchase, and it was difficult to find a quality device for a reasonable price that included solid state storage. ASUS has shattered that barrier with a 256 GB SSD at this price point.

They have also changed the perception about design and feel of a mid-priced notebook.

    Great article and I think u need to include a new metric such as clarity for touch screen optioned laptops. Recently i purchased a Asus UX303L with the 3200x18000 touch screen. I was devastated to be able to see the touch screen gridlines that were extremely visible. I checked out the dell XPS and samsung touch screens with the equivalent resolution and the grid lines were not visible. Since I am in Hong Kong, no refund is available to consumers and im stuck arguing with asus support that this is normal. If i had noticed those lines i would have bought a dell xps instead.

    I was about to buy Lenovo U41 I5-5200 U Processor, 4GB memory, SSHD 1TB 7MM 5400RPM,but I disappointed just because of its TN display and very poor screen quality:-(

    I just came across Asus UX350 & really impressed by its spec, but following are my major doubts blocking me to buy this,

    1.I am a software developer,
    Will be using ORACLE DB & Eclipse & Web design & Music running simultaneously.

    Will Asus UX350[Core M5Y10] can handle it without crashing and more heat?

    2.Fan less processor will be good even after one year???, how it cools up the ultrabook?

    Please suggest if you know any other model for my below requirement.
    No Compromise :
    1.13 inch screen - IPS is Preferred
    2.Slim & not more than 2kg.
    3.Good processor & RAM , which easily supports ORACLE DB & Eclipse & Web design & Music running simultaneously
    4.More than 5 hours battery.

    Can be compromised:
    1.Storage size is doesn't matters if its SSD or else 1 TB/500GB sshd.
    2.Price around INR 50,000.

    I admit I am a bit of an ASUS Zenbook Fan(boi), I do or have owned 3 ASUS 'laptops' (UL20A, UX32VD and a Transformer T100). But one thing that really, really peeves me about their keyboards, having the PgUp and PgDn (and to a lesser extent Home End) on the arrow keys thus needing to press the Fn key to get those functions. Especially when there is plenty of room on the keyboard (above the left and right arrow keys is room for PgUp/PdDn).

    Having 1-handed access to PgUp/Dn is extremely useful to have in a small laptop, as I tend to lay in bed/floor/couch propping up my head with one hand while reading/scrolling/surfing with only one hand. And yes I know how that sounds ;)
