I only use one screen since I'm a minimalist. I don't like having to flip between screens with cluttered apps all over the place. I only use twelve apps on the one screen I use as my home screen:

1) Quicksettings
2) Browser
3) Google Voice
4) SIPagent
5) Camera
6) Shazam
7) MixZing
8) Voice Recorder
9) Android Market
10) Gmail
11) Documents to go
12) Google tasks (browser bookmark set as homescreen app)

I use all of these throughout the day so anything else goes in the normal app drawer. I absolutely hate clutter and love open space so I organize my home screen accordingly

 

Congrats on getting the N1, I would check out this thread to see what other people are doing with their home screens:

If look around this site you will find these types of threads everywhere. It's a good way to get ideas and learn about apps/widgets that are out there.

 

They have a thread called post ur screen shots. ..justsayin
