The compact laptop mouse is especially suitable for transport. The name says it all: it's compact and slightly smaller than a 'regular' mouse. A compact computer mouse takes up less space when you take it with you in your laptop bag. This way, you can continue working on the train when you're on the road. You can spend your travel time efficiently and answer those emails in your mailbox faster. You'll have more free time when you're at home and your contacts will know where they stand. Decide whether you prefer a wireless model or not.
