~~~1 year Update~~~
I have downgraded the score from 5/5 to 4/5. This laptop is, for the most part, great. However it has several very serious flaws including: Terrible trackpad, bad monitor, and bad sound.

-Performance- 3/5 [Average]
Very powerful specs. This laptop may not be a gaming laptop, but will play most things you throw at it very well. Including AutoCAD, SAP2000, light games, and Movies.

-Build- 5/5 [Excellent]
All in all, its built very well. The exterior, as you can see, is beautiful.

-Keyboard- 4/5 [Good]
The keyboard looks and feels very nice. The keyboard is slightly narrower than usual, which makes it feel a little awkward. But I haven't had any problems typing.

-Trackpad- 1/5 [Terrible]
This trackpad is a piece of junk, after using it for a year, I've learned to use the "F6" -turn off trackpad button- more than 90% of the time.
I have also disabled "tap to click" and "multi-finger gestures." Left/Right clicking is a nightmare.

-Monitor- 2/5 [Bad]
The monitor is 1366x768. Which is pretty disappointing - but it the norm for 14in laptops and even 15in laptops. The colors are a bit washed out, and I really notice it when I have my laptop next to my desktop monitor. There is definitely a sweet spot for using the monitor, and its pretty small. The hinges don't let it bend back all the way. I'd say, you get about 135 degrees of motion on the hinges. This laptop also has terrible viewing angles.

-Sound- 2/5 [Bad]
The speakers on this laptop just don't push enough. They are useless in most enviroments that have ambient noise. The quality of the sound itself is pretty average.

-Weight- 5/5 [Excellent]
It's pretty light weight.

Follow up - So it's been almost a year since I got this laptop, and I would have to say...I have to change my original rating of a 5 to a 1 star. Over the period of time, my battery itself started to have problem, my laptop stopped staying cool, and I had issues with it twice. 1 of 2 times I had problem with it, I had to figure it out myself, because the customer service was just horrible. I mean the computer itself is still pretty good but the change to a one star is mainly because of the customer service. So basically, my laptop had a blue screen. Keep in mind, I keep my laptop in very good condition physically. I got my laptop sent in to the repair center and after 1 week, my repair status remained the same. I gave them a call, and I was told that I had water damage in my motherboard and I would have to pay $360+ some fee in order to fix my laptop. I told the rep that I never had water spilled on my laptop ever. She then mentioned that I had some water mark on my keyboard...I proceed to explain to her, I washed my keyboard with a very damped cloth before I sent my laptop for repair, and she tried to explain to me that might had been the problem. All in all, after speaking with a few other reps, I didn't get my problem solved. They insisted on me paying $360+ some fees I couldn't understand. Felt like I shoulda sticked with a brand I was more familiar with and listened to those who said the customer service was horrible. The laptop cost $600-700 bucks now for a new one, so I didn't even bother paying for the repair, hopefully I can retrieve my harddrive datas.

This thing is pretty amazing!

I needed a new laptop after having my previous one for 4 years. I love windows (not that I have anything against Mac OS, just don't prefer it), but I wanted something with the build quality of a mac book pro but a lower price tag. I was really considering getting a mbp, until I saw this laptop. If you are in the same boat as me, then this is the perfect laptop for you. All aluminum body, extremely sturdy look and feel, very sleek design, I would say it matches up perfectly with the mbp but at $300 less.

The thing runs extremely fast. The 2nd generation mobile i series is catching up to the power of the desktop versions. I really don't notice a difference between this laptop and my i5 desktop tower as far as responsiveness. Trust me, performance is not an issue for this laptop. It can handle anything that you can throw at it (obviously that's an exaggeration, but anything reasonable that you can throw at a laptop it can do). It also runs very cool. mbps get hot, especially when setting them on your lap or on a cushioned surface. The cooling out the side and through the keyboard of this laptop makes it stay cool and keeps the bottom of the laptop from becoming a personal heater (which may not be a good thing if are use to using your laptop as one).

The one area I would say the mbp beats this thing hands down is the screen. The screen on the u400 is 1200 x 768 and doesn't look as sharp and clear as the mbp's screen. I like running my screens at really high resolutions even though it's probably not great for my eyes. But it is only a 14 in screen and a higher resolution probably wouldn't make sense. Another small flaw that seems to be common is the screen not closing perfectly flush around the entire edge of the laptop.
