"S431 is the best ultrabook one can get under $700. A perfect alternative to a macbook. I recommend the SSD hard drive for S431. It definitely improves the overall performance of this laptop. Also consider to upgrade the processor to i5, if you emphasize the processing speed."
"My father has been using a Lenovo for a few years now and only had good things to say about. So, when my other laptop died I jumped on the opportunity to try a new brand. I was blown away by the S431. This is my first ultrabook and I absolutely love it. The backlit keyboard is a nice change of pace. This machine doesn't make a noise when it is on. With the SSD, boot time is lightning fast. With the USB 3.0 having media on an external HDD is perfect. I am a student and the portability is so wonderful. It's pretty light and it feels wonderfully sturdy with a quiet keyboard that doesn't distract others in the lecture. I love it."
"I have a desktop for home; I bought this laptop for school/work use and travel. I do programming in programs like SAS and R, so I needed something with a fast processor, 8 GB of RAM and Windows 7, but also something relatively light. This was the perfect compromise for me in terms of price vs performance (I'm a graduate student, so I didn't have a ton of money to spend). The battery life is decent (4-6 hours for me), but 8 hours would have been nice. I have the HD+ (900p) screen; the colors aren't the best I've seen, but for business/work/school use, it's perfectly adequate. The keyboard is comfortable and the trackpad is good for a trackpad. This is the only ultrabook I was able to find under 4 pounds that included an I7 processor, 8gb RAM, dedicated GPU, and an SSD for under $1200."
"Overall this is a great laptop, and it definitely suits its price well. Feels firm and incredibly durable. Mine is i-7 with 8 gb of ram. Performance has been outstanding so far. Heat was never an issue for me with this machine, although I loaded it pretty heavily. It handles any hd video just fine. The only reason I gave 4 stars is for battery. With active content consumption (checking e-mail, with wi-fi always on, watching hd-videos, and installing applications) battery drained in 3 hours. However, I am sure, with a normal days load the battery will last 4.5-6 hours as described. It lacks VGA port, which is a con particularly for me. Overall, it is very nice laptop, with GREAT keyboard and cool design."
"The hybrid drive is extremely fast compared to my old standard hdd. Battery life has thus far been spot on with advertised 6 hrs. I like that the volume, screen brightness, display source, etc, are all hotkeys. It makes for a less cluttered keyboard. 14 in screen is so much better than the 13 or 11 in screens you normally see on ultrabooks.
This system combination does indeed require a good bit of ram (2.5 gb). I suggest the 8gb ram upgrade. I also suggest the HD+ screen upgrade. Trackpad click is a bit noisy for center click and there is also a learning curve associated with it. Once I got the hang of the trackpad, I found it very rewarding. Speakers are adequate but I use a Bose speaker system when working at my desk. Could use one more USB port (even if only 2.0)."
"cons: no light on CapsLock button, TrackPad too loud, right-click area not accurate/sensitive, screen contrast is weird, colors not vibrant, screen strains the eyes, battery drains completely in 2 hours in High Performance mode, feels a little flimsy, no dedicated volume control buttons; you must press "Fn" plus another "F" button for functions, weight on the heavier side for an ulrabook
"Overall a great ultrabook. Its great as a mac alternative, yet you must be careful with the screen around the bezel. It was a great price, and It is a great laptop for students who treat their laptops carefully (not me :(). The ultracharge battery plus a haswell processor would be a very interesting combo. I hope lenovo makes this happen in the future."
Cons: Input/Output compatibility, Battery, Included Software, Display performance
"Have the Core i7 Processor, 8GB RAM, discrete graphics, 500GB HD + SSD
Keyboard and TrackPoint set it apart from other computers. Clickpad is too loud and goes down unexpectedly far when clicking.
The HD+ screen has good resolution and brightness, but the color isn't quite there compared to other monitors.
Typical battery life has been 4.5 to 5 hours, with 6 advertised. I'm using Windows 7 so that might keep the battery life down. The Bluetooth chipset is power hungry and I've seen a noticeable difference when turning it off.
Hard drive and SSD work unobtrusively and haven't given me issues. Goes in and out of hibernation really quick when using the SSD"
