Even if I granted you your complaint about comparing a phone to future options, my statement would still stand under the weight of all the other things I mentioned, as they have superior counterparts already on the market.
Now as to comparing something to future options, it is in fact a valid point, as the best phone ever made would have been made with the greatest future proofness it could achieve, and the makers of the best phone ever made would have observed the coming rise of quad-core, and would have decided to wait to include them in their device before releasing it.
And btw, DeLoreans do exist, and have existed since before that move was made.
