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.

    Why micro HDMI? Why a port nobody uses?
  • Novacius - Wednesday, March 25, 2015 - link

    A full sized HDMI port would be too big I suppose. This device is only 12.3mm thin.
  • baka_toroi - Wednesday, March 25, 2015 - link

    What do you mean? You mean nobody connects a notebook to an external display? If that's what you're saying you're wrong. And HDMI is much more universal than Displayport.
  • Gigaplex - Wednesday, March 25, 2015 - link

    But micro HDMI isn't so you'll need an adapter anyway. Mini DisplayPort is more common than micro HDMI thanks to all the cables that cater for Apple machines.
  • xthetenth - Wednesday, March 25, 2015 - link

    Because they make micro to regular HDMI cables allowing users to connect to HDMI monitors, which covers a huge fraction of external monitors. As somebody driving a 3440x1440 IPS out of a laptop every day, this makes a huge difference in how useful a laptop is.

    Indeed, I would have expected a mini DP video port.
    But it does make sense, actually. Micro HDMI is not very common but has the advantage of being able to be hooked to almost any display on the market, without an active adapter. Except for extremely-low-level models, all monitors have at least one DVI or HDMI input. DP connectors are not so common. So this is a very cheap choice for the end user since simple passive microHDMI to HDMI or (micro)HDMI to DVI adapters are sufficient.

    I don't think you have any idea what you're talking about. Mini-hdmi does not have any advantage whatsoever above miniDP.

    Both connectors:
    Connect an HDMI or single-link DVI display with passive cable.

    MiniDP only:
    Drive higher display resolutions than 1080p (i'm not kidding. The old zenbook was limited to 1080p), drive VGA, miniDP or DP displays with an passive cable, dual-link DVI with an active cable. Adapters are quite common due to the popularity of macbooks.

    mini-hdmi only:
    licensing costs.

    The ONLY reason to choose mini-hdmi over miniDP is marketing.

    Thus the prominently placed HDMI sticker on the palm rest.

    All the projectors at my workplace have an HDMI port. Seems pretty useful to me.
