This new update will enable you to use a normall USB Keyboard instead of using the Wiimote and on-screen keyboard, you will still need to use the Wiimote as a mouse though. I hope soon Nintendo will bring out a proper wireless Wii Keyboard called a Wii Board =).
( Please note that some USB keyboards may not function correctly. Nintendo recommends the Classic Keyboard 200 from Logitech. - From http://www.wii.com/ )
