Summary: I bought this laptop for my wife and I am happy to say that it meets all my expecations performance wise. It's light and sleek and fast. I reformatted it after getting it because companies always muck up computers with extra worthless software.
Summary: My Asus is so light, starts up quickly, and I love that the wireless turns on instantly instead of my computer looking for a signal, connecting, etc. My only wish would be for a backlit keyboard.
Pros: Thin, light, powerful. Quality display, though I'd prefer a matte finish. Plenty of port options (HDMI, USB 3.0, etc). Keyboard is fantastic, as is the overall build quality of the case - no flexing.
Cons: 5400 RPM HD, really? C'mon now. Upgrading to a Crucial 256 SSD in the next month. Hard drive is NOT easy to access, minus one star for that.
Summary: Best overall laptop I have seen/used. I run 3d modelling programs, rendering, photoshop, etc - all on the battery, and still can squeeze a 5 hour flight out of it. It's the true architect's laptop. Light enough to chill with on the road, but strong enough to turn it up a notch.
Pros: Battery life is great, features are great, I/O ports are great, Weight is great.
Summary: Thumbs up for the design and speed. Alumunim and Magnesium coating makes the Asus U36SD's thin and light feature indeed "cool". Downside on the sound quality (compared to Asus K and N series model) and for the heat that comes off on the areas around the keyboard.
Summary: I've been using this U36SD-DH51 for the last couple weeks, and I love it. It is thin, light and fast. The battery life for regular stuff like web browsing, even with the screen brightness up, is about 7 hours (though I fully expect that to wane as the battery ages).
Summary: Update, buyer beware. Have used the machine for about two weeks and have to say that it appears to have problems with communications. In addition to the defective Bluetooth module, the WiFi card is not very good. In order to get a strong signal the machine has to be almost on top of the router.
Summary: I purchased this laptop after reading thousands of reviews. I wanted something light (<2kg) with long battery life (>7h), small and powerful (>intel i5). I was considering other options like Acer S3, asus UX31, sony vaio SB/SA series and Toshiba Portege R835.
Summary: I got the equivalent U36SD-A1. I love the construction and speed of this computer. It is a little heavier than an Ultrabook or Macbook-air. But, you get the benefit of a fully powered i5 even running at 3.0GHz well ventilated. I think this is the way to go.
