Well I got a Rev. B mail order today (128G SSD model)...it's plagued w/the downward sloping horizontal lines. Rather than try to bring it to the Apple store and deal w/having to get a repair or convince them there is a problem, I've decided to simply return it. I'd really like to upgrade to the Rev B w/SSD, but don't want to play roulette hoping to get a model w/out lines. Would the best bet be to go to an Apple store, pay a premium for buying there and just return it on the spot if there are lines?
