Here's a good reason: in April 2014, Microsoft stops issuing security patches for XP. At that point, any exploits people find(and they will find them) will never be fixed. Your computer will be the easiest target out there.
Not just will this be bad for you(assuming you value your files or do banking on your laptop), but if your compromised computer starts hosting a botnet or attaches viruses to your emails to friends, it's a problem for everyone.
It's a similar problem(though not nearly on the same level) as people who refuse to vaccinate their children.
