ASUS just announced its first line of Ultrabook PCs under the new Zenbook brand at a press event in NYC. There are a total of five models in the Zenbook lineup ranging in price from $999 to $1499 and available in both 11.6-inch and 13.3-inch display configurations. Based on specs alone, the Zenbook lineup is very similar to Apple's 2011 MacBook Air. Dimensions are almost identical, although ASUS' 11 is a little heavier than Apple's while its 13 is a little lighter. The entire Zenbook lineup ships with 4GB of DDR3 memory and all of the systems use the same ULV Sandy Bridge parts that Apple uses in the MacBook Air. Battery capacities are identical to the Air models at 35Whr and 50Whr depending on the chassis size. ASUS does claim lower standby numbers than Apple (up to 10 days vs. up to 30 for the MBA), but that's likely an OS limitation. The Zenbooks typically give you a larger SSD than Apple (and 6Gbps on top of that) as well as a single USB 3.0 port to complement its USB 2.0 port. ASUS claims a 2 second resume time for all of the Zenbook models, presumably from a suspend-to-RAM state.

The first Zenbooks will be available for order in the US starting October 12th. I've included some head to head comparisons between the various Zenbook models and their MacBook Air counterparts below. For the most part the specs aren't all that different. I don't expect that there are a ton of users who cross-shop similarly priced Macs and PCs, the Zenbook simply looks like a good option for those users who want a MacBook Air but prefer Windows 7.

ASUS' 13-inch offerings do have a higher resolution display than their Apple counterparts (1600 x 900 vs 1440 x 900). We're still waiting to hear back on the panel technology used in the Zenbooks, but I would be surprised if it was anything more than plain-old-TN like the Macs. Compared to the upgraded MBAs however, ASUS' Zenbooks do offer higher clocked CPUs at the same price point.

    1. What is the support of the GeForce GT 650M GPU for ubuntu.. i have researched and found that if this notebook's bios doesnt support any option to use nvdia GPU by default.. there is no way that nvdia gpu can be used from ubuntu or for that matter any of the linux distros.. due to the optimus functionality by nvdia which is nothing but auto switchover of the intel/nvdia gpus to optimize performance.Any clarification on this?
    2. The ram is 4gb soldered on to the board.. fine but there is one slot on the board that supports removable ram.. so how much ram this notebook suppots? 4+8(pluggable) =12GB ??
    3. The battery is also soldered on the board.. as i have experienced in the past the batteries dont last max 1.5-2 years.. so what options do i have for a replacement of the battery dies out.. paid support from asus is also fine... but it should be possible as i dont plan to throw this notebook away say 2 years from now.. atleast 4 years i am planning to use this one.
    4. What about the warranaty?? is it 2 years international one?? as its not available in india.. i might be buying from the US for use in india.. so will i get warranty support here in india??
