Well working with your laptop on your lap is not practical for most people to begin with, therefore I'm not seeing a problem with providing a solution to at least have a better typing experience.
And I don't think what I described is that uncommon, there are plenty of people using this combination...

Obviously if you're having to work with your laptop on your lap for 8 hours a day without wanting any external input devices and still require a very specific typing experience then there might not be too many options out there...
Unfortunately I don't have a reply for this as it seems the topic of conversation has drifted from 'I do this, it is fine' to 'well this isn't practical but nobody does that anyway, nor should they'. I only have issue with the first case, I won't refute your personal experiences.
I don't see how stating something being fine for me and something being impractical for most people is a drift in a discussion. But in the end you fortunately did have a reply to this! (which is good, since that's what discussion forums are for...)
