My first macbook is going on 6 years old this year, but it needs some work and I'm currently too lazy to do it.

Work gives us laptops, with a second monitor, a docking station, keyboard, and mouse. So I get the full setup at the office - but I need to be able to take it with me when I'm on the road. I've asked them several times, why do we have the heaviest laptops in the world if we have them for portability? My back prefers lugging the macbook around, by far. If they really wanted portability, we could have full desktops at work and a netbook/tablet/small thing to take on the road with us.
