The only place I've ever seen it to be an issue was for a while in the UK they would randomly pick one as they came through and look for kiddy porn on it. They even had a warning not to have any on your laptops as they were looking for it.

You should have no problems at all, if it's brand new you may want to either register it with customs or make sure you have a sales slip so they don't try to charge you duty on the way back in, but in general it won't even get looked at.
