I dunno - updates are far less frequent now, haven't done one for what feels like a year. And the interface is excellent, what you on about? Everything's right there, a click away.
Why are you lot complaining about updates anyway? You want games with bugs? And I look forward to PS3 ones since they generally add something cool.
Like I said, this is all 'in my limited experience'. The updates were just an example; on the Xbox game updates take seconds, I've done a full system update in about two minutes. The PS3 in contrast always took forever.
More exposure to it might easily change my opinion. I don't own one.
