I've had it for about 4 months now. It's a good computer that is severely crippled by a spindle hard drive and some of the crap the domain admins push on us via GPO. We're getting a new set of W520s in the next couple weeks that have 16GB of RAM and an SSD, so we'll see how those puppies work out (I should be getting one of them). I do software development, BTW, if that helps.
