If you're going to use external mouse/keyboard/monitor/speakers/etc. when you're not on the road, you'll probably want to look into a docking station or port replicator. That way, you just need to slide the notebook into its dock instead of connecting all the various cables and whatnot.

HERE is a link to a port replicator for the Evo N610C on the Compaq/HP online store. You may be able to find it for less elsewhere.
