Mysterious friends

I appear to have picked up a new friend.
I just haven't a clue who they are.

Netbook

I've come up with another good excuse for buying myself a netbook:

1. My OU course comes with a DVD.
   
2. I'll probably work better away from home.
   
3. I'll probably do all my work electronically.
   
4. My MacBook is too large to carry easily, and it's dying a bit.
   

From this, I think we can conclude that I need a small, easy to carry something that will allow me to watch videos and write on the go. ergo, I need a netbook.
