Pamster, I've decided not to install the updated touchpad driver, at least not now, anyway. I'm getting used to it for the [very] limited amount of time I actually use it. I'm using a Logitech Anywhere Mouse MX, and I absolutely love it! It comes with a unifying sensor the will also work with their wireless keyboards (not that I'll ever use one of them, but it's a nice option to have).
I'll keep the driver software stored with my other drivers, but for now, I'll stick with the status quo.
Now, if only my Bluetooth and WWAN cards would get here from Dell!
