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. Without all that bloatware this thing rolls along smoothly.
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.
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. You need a cooling fan for this "hot" laptop.
Summary: I got one of these because I got tired of lugging 20 lbs worth of Alienware m17x back and forth (when hoofing it, this required a serious backpack with an internal frame to protect my back). That m17x had a serious Quad Core i7 processor, 256 SSD and 16 GB RAM on it and I had doubts that this U36S ultraportable was going to be able to sustain my workload.
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). The case and the keyboard feel solid, and typing is comfortable.
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. I have the machine located about 20 feet away from the router and the signal averages 2-3 bars. When I carry the machine to the router, it goes up to five bars.
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. S3- I am not a fan of Acer and it came with the SDD which I found too small. UX31- It is really good and nice but it has less connectors and was too expensive. Not sure if it can be upgraded.
Summary: So, I was searching for a Laptop with nice performance, which was portable, and had long battery life. The U36SD has all three, plus a great build quality and finish. A few things to notice, though: -First, it does come loaded with Asus' software, but uninstaling the unimportant applications is all that is needed, since I didn't notice any slowdown when compared to a fresh Windows install.
