I have given 4 because there are many better ultrabooks in the market and people are so obsessed with asus. It has 99% copy design of the flagship macbook air and just some paint work done to look different. Its trackpad is the worst i've never experienced and an uncomfortable typing.
It has hd+ resolution which is great as it is the first to come up with. But screen seems to be white torch with improper black color production. Infact toshiba Z930 screen looks better to me even though zenbook has 450 nits panel. Its earth current on the top of the panel makes it irritating if you leave it for an hour.. once you touch you get shock.

Really quite a fantastic Ultrabook. Speakers are really impressive given the size and location and the speed of the notebook is simply fantastic! Zero lag time work watching movies or playing games like football Manager. Dun think the graphics card can support HD games though.

Multi-tasking (Running itunes, word, excel, outlook, bitcomet, matlab concurrently) does not seem to slow down the system at all and every task or window that i switch to is equally responsive.

Ultimately, I'm impressed by the size/thinness to performance ratio. Will recommend to all my friends!

9 rating because a number of people has told me about Asus laptops being not too durable.Hope this notebook proves otherwise.
