I'm fine with it. All my account has is a name, email, and adress: not much they can do with that. Hopefully though this helps Sony in the future when trying to sue hackers and such.
You aren't thinking like an attacker experienced in monetizing this sort of data.
In addition to getting you account name and email address, they also got either your password or a hash of your password. While your PSN account password may be unique, most people use the same password everywhere. Armed with an email address and password, attackers will typically check the password against other services such as Amazon, iTunes, PayPal, various banks, etc. If say, your iTunes password is the same as your PSN password then the attackers can make several high-value purchases to songs or apps that they own to make money.
Also, your email address tied with a real name and home address is a lot more valuable to spammers and marketing companies than just your email address alone.
Another way to monetize your information is to use your username and password to log into your Facebook account. One such scam is the "stuck in London" scam to con your friends out of money.

Finally, usually the people that hack the information don't try to directly use it themselves. Usually they offer the information for sale to other scammers that are setup to perform specific attacks. They will offer valid Facebook logins for sale as well as valid iTunes logins, etc. Somebody who is used to stealing money via iTunes will buy those logins in bulk to try to steal money.
In short, your data is for sale and even if the original attackers can't think of a way to make money from the data, they will sell it to others who can.
Everyone affected by the breach should take all remediation steps necessary to devalue the stolen data as much as possible.
