Oh.. there's a moment... coming. There's a moment coming, it's... it's not here yet. It's on the way... It's still in the future. Here... here it is! (a beat) Oh.. it's gone, man. There's no present, man. Everything is the near future and the recent past.
-- George Carlin (1937 - 2008)
If we allow these questions, we're begging for what are essentially duplicates later on, when the next generation comes out. These questions by definition get outdated, and trying to revive them later is frankly ineffective.
With the ever-advancing state-of-the-art, these questions (to me) should be treated the way Super User tries to treat shopping questions (as that is what they are): Shut 'em down. They'll eventually be just noise.
