At my previous work we used docking stations for the laptops. So at desk I had my big 22" monitor, mouse and regular keyboard connected to my laptop and whenever I am away I still had everything that I worked on with me. Then again I was a manager so all I had open most of the time was Thunderbird and Excel. I don't know if the extra pixels helped in my case ;). In any case I would recommend that setup for work.
