More productivity on a notebook?

I am realizing an interesting thing. When I work solely on my Macbook just with a mouse I get done much – and I mean it – much more work as opposed to when I work behind my desktop with a big 24″ screen.

It’s like with the big screen I focus too much on details – especially when designing and doing front end/GUI stuff. On the 15″ Macbook screen everything is more compact. Less information to process, more focus possible.
