The antenna issue is real and worse than other phones because of the design they chose (putting it on the outside of the phone). Fortunately, the fix is simple and the rest of the phone is excellent - particularly the screen. If I had one, I would get the zagg clear strips to cover the antennae so as to preserver the original look.

I think there are bugs with any new technology that comes out. I'd say if you are really worried about it, wait a month or few before purchasing yours.
