I had one for 2 years that had no keyboard problems, and then the alt key required more and more pressure until it stopped working completely. I finally had enough and took it to sprint to replace since I had the insurance. The THREE refurbs in 2 weeks they replaced me with have been even worse. It's never the same keys and there is usually a combination of some insensitive keys and some oversensitive keys, so it's not just a matter of typing everything harder.
