Comfortable partition size?

[David Stubblebine]

I just put a roomy 120 GB drive in my Dell C800.  What is a  
"comfortable" size for my ubuntu partition?  And can it be resized  
later using ubuntu tools (i.e. without having to buy partition magic  
later).

I know it's entirely up to what I am going to do with it - I am just  
at the experimenting stage now.

Thanks for any advice.
