No, not really. It’s nothing new, just an attempt by Sony to try and even out the interfaces, although Home might give them a boost if it ever gets out of beta.
Achievements/Trophies are wastes anyway. I miss the days when unlockables in games were actually content, instead of having to pay $5/$10 for things that should have been unlockable or in the game anyway. It just means that those few games that are PS3 exclusive will just be burdened down with Trophies instead of real unlockables.
