I just wish the people on my friends list would get rid of their avatar gamer pictures. When I hit the guide button to check the list...it takes FOREVER to load all those custom avatar pictures. The friends who have the "classic" non-avatar gamer pictures load up within 2 seconds.
The NXE is so damn slow it drives me nuts on a daily basis. Love the "install to hard drive" and party system features...but everything else is slow, advertisment-filled, crap IMO. I'd happily go back to the 5 "blade" style if I could.
