In terms of the pros and cons, I think it is safe to say that wired is always preferred over wireless where available. The pros include having a connection that is not susceptible to interference by cordless phones, microwave ovens, neighbour's wireless routers or phones, etc. Wired is also still a faster connection at up to 100 Mbps (although if you get wireless connections at 54 Mbps you probably will not notice the difference). Also many people are still concerned about security as although having a secured wireless connection is generally quite safe, it is still potentially susceptible to someone with the right equipment, knowledge, and a lot of time on their hands as well as intent.
The cons are pretty much just what you explained - running the wires and drilling holes. It could potentially be negative from a cost perspective as well depending on what physical changes you need to make in order to run wires, and just how many computers you are running to and where they are. You can usually go to a home renovations store and get ethernet (category 5) cable for a very reasonable price and end up paying less to run the wires rather than purchase wireless networking cards if you do not already have them. If you do already have wireless networking cards in all computers, then there isn't much of any price difference between purchasing a wireless router and a router that does not have wireless capability.
To sum up, I would go with whatever is easiest. If wired is not that much trouble though, I would still recommend that method as it offers the most reliable connection.
