Look into QuickOffice.

I use mine everyday.   I read a book in bed several nights a week.  I play a game or web surf in the evening.  On Sundays I use it to take sermon notes. 
I use it at work to jot down notes.   When I go out of town on a service trip,  it is used to keep track of what I did,  my hours and expenses.
I keep important documents on it so that I have access to them for reference even without my PC.
It's even been used to remotely access my Linux computer at home when I am at work or out of town. The tablet size makes this much easier than on my Droid.
