Is NE2 worthwhile? I just realized I'm a week away from it, but the discount is only $50. Huh? If I want a Samsung Fascinate (which I think I do, as my other purchases of phones haven't panned out), then I can get it cheaper as an upgrade from Amazon ($99 upgrade) or Best Buy (free on Friday maybe?). What's the point of it? Do you bother using it at all?
