A couple days ago I changed my XBOX Live Gamertag and I wanted to change my PSN ID to match. When I went to look for info on how to do it, all I saw were sites saying that Sony doesn't  let users to change their PSN IDs. The only way to get a new PSN ID is to either create a sub-account or to create a new account and both of those options seem a bit unnecessary just for a new name. Is there an actual reason (technological, legal or otherwise) that Sony doesn't provide a name changing service?

Probably because their system isn't as flexible as Microsoft's.

as far as i know, Xbox live is one of a few of services that let you change your id, but you still have to pay. blizzard does it also for SC2 but you still need to pay. im not sure, but i think steam is a service that doesn't let you change your name.

Same reason Giant Bomb doesn't allow user name changes: you just can't. 

It is kind of lame that they don't let you. They should add that feature and just charge money for it like the 360 does so people don't spam there name changes.

I've been tempted to start a whole new account just to get away from my PSN name :/

I'm guessing because since you can make accounts for free they don't want people changing it all the time.
