My wife has a Lenovo notebook primarily because the keyboard wasn't outright horrible. Many of the Dells at work, all Latitudes (business class) have reasonable keyboards... nearly comparable to the Lenovos.
FWIW, per Sony, one of the notebooks we saw at Office Depot was a Sony and that particular model had a horrible keyboard. It had keys that resemble those metal keys on ATMs, and the key feel as numb and heavy, not to mention the lack of tactile feel from the flat keys. I remember disappointment, as it felt like a quality, rugged keyboard... just not-so-good to type on.
