Now when Sony is pushing the store; I do think they should enable XMB access from the store... so it feels more integrated into the PS3 system. Also I think Sony should use the logotype included in the news, together with the background when the store starts up or when hovering the icon in the XMB. That thing that popups there looks plain nasty (same goes for Photo Gallery!).
Otherwise it sounds great!! Keep it up Sony
... it's good for us, the customers!
A bit off topic: Sony, change the white "PlayStation 3" text and sound effect (when starting a game) to the text + sound effect you're using in ALL your trailers!
