There are only so many well designed fonts in existence that stand out and look different from each other. Maybe Sony already owned the rights to that Font so decided to use it again. Definitely looks OK in my view.

I think they wanted to give the PS3 more of a complete home entertainment feel with the new font, compared to the existing Playstation fonts used in the past that have mainly been associated with gaming only.

And that is good news about the memory card adaptor. Is that a Sony or third party product?
