I understand that to keep the size of the 12” iBook as small as possible, Apple had to make some hard decisions about which keys to leave off the keyboard to save space.  Unfortunately, some of the keys are the very keys I use all the time.  Page Up, Page Down, Delete (not Backspace), Home and End are all keys that did not make the cut.  I really think that if they cut down the size of the mouse button, they could have gotten an extra row of keys on the keyboard at the top the size of the function keys.  The addition of those five keys would make my life a lot easier.  Yes, I am aware that I can accomplish all those functions by using a combination of keys, but that requires two hands in most cases.

I really hope that when Apple introduces their Intel based laptops they will find a way to include those keys on the keyboard.

One more thing…how about a right mouse button?
