I meant that it's faster to navigate like that then using the dashboard... It's still much slower then the old dashboard and IMO the old one looked better.
My xbox has had similar lag problems in Halo CE but that's it.
I think this one looks a lot better, its a lot more graphically good-looking IMO.
I agree that the old one was a bit quicker on the dashboard such as loading XBL MP content, but the guide is a lot faster and you can do a lot more things that you couldn't before.
