I forgot to mention the trophy part of this - putting aside my feelings of trophies, I think the trophy aspect is just going to be another hassle.
you get a trophy and you make a special place for it in your room. You arrange them so you have your awesome ones up front and the piddly bronze ones more out of sight. Your room looks awesome with all your awesome equipment and trophies.
The problem is that somebody has to come to your apartment to see your awesome setup. Again, that's a hassle. Why the fuck would I want to take (at least) minutes to see that when I could have something like XBL where I just click a button and I can instantly see all your achievements (and I assume the XMB has something similar)?
My point about Home is that everything is done better through the XMB. People do like flashy graphics but they also like to save time. Home is flashy but it wastes a lot of time and that will be its downfall.
