Ha ha, I only use the trackpad when I have to as I always touch the screen otherwise. The only time I have to use the trackpad is for precise selections (or when I'm not using the pen as well). I've got so used to interacting with the touchscreen that when I go back to my work Lenovo laptop I keep prodding the screen and expecting it to do something!!
I like the keyboard cover, I don't feel the need for anything else and find the typing experience fine, if a bit "clickity clack" on it. I do like that it's backlit, mad really when the keyboard on my husbands £600 ASUS laptop is NOT backlit, which is a right pain when I use it in the dark often to control lighting at discos, the past couple of times I've actually used the surface instead as I prefer it!
