wait what? NXE is a new UI that finally brings the 360's GUI a modern look (XMB>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>dashboard. heck, it even won an Emmy...), adds a copy of Miis, and a few other perks (party/netflix/installs) the latter two of which have nothing to do with the UI/Home. (though I AM jealous of installs >:| )
So yes, Home is old, but NXE doesn't put Sony in catch-up mode anymore than they already were to XBL. If anything, it make XBL look bad by playing catchup to Sony and Ninty.
Not trying to be a fanboy. Of course, it's hard when you own the best console eve... dang it
