Summary: Not bad. I have had a handful of issues but most of them very minor, and don't impact the functionality of the machine. My only knock on this laptop is that it cost way too much for what it is. Yes it's very fast, but overall quality doesn't justify that price.

Summary: Let me first describe what my motivation was to pay about $1400 for the "state of the art" Laptop. My first encounter with a Thinkpad was in 2003 and it was a nice experience using that Laptop for several years. Several years after this, I had to use my wife's laptop for a while and it was so slow and it got me so frustrated that I decided, my next laptop would be the fastest and most reliable laptop that I know of: a Thinkpad.

Summary: Replaced a Macbook Pro with this laptop and 3 years later it's still running great. The 1920x1080 matte screen has great color reproduction and doesn't show reflections at all. Cooling is excellent, I can run the CPU and GPU both at 100% and the temps stay in the low 70s celsius. All four cores boost to about 2.5 ghz. Ergonomics are very good and the keyboard is the best you'll use on any laptop.
Summary: I've been using a W520 for over 2 years. Very reliable, have not seen a crash even when it is very hot because of playing game. I upgraded to 32GB RAM and 256GB SSD, awesome, I could simulate a whole server stack for enterprise applications on it. Sometimes I play Starcraft and World of Warcraft, it performs well in High quality graphic + Full HD resolution.
Overpriced, totally unreliable machine. The worst computer I've ever owned

Summary: On paper, this looks like a good computer. The hardware specs make it out to be a solid workhorse, which is probably why my company provides them for its entire consulting team. But in practice, this thing is a piece of junk. In two years of use, I've had to replace the hard drive (bad clusters), the DVD drive (it simply stopped recognizing any discs, most of the time), and I've just gotten off the phone with tech support staff who say that my SD card reader’s failure...
Summary: Higher performance than same priced new models, many interfaces, excellent chassis (durable, though light), easy to add/replace parts. Last model (T520, W520...) with the old-style Lenovo keyboard, which has much better layout than following T530 models. The keyboard light is almost useless on this model but this is of no concern to me. This model supports m-SATA SSD, which is great for use as a system drive.

Summary: An expensive heavy labtop with great specs on paper but in reality it functions really poorly. - I bought this machine two years ago and just 6 months after the battery died. Good that it came with one year warranty so they sent me a new battery. - the mic didn't work well and I could never fix it and I always had problems on Skype and other application as nobody could hear me very well.
