A bolt's not theft proof, but it will stop some annoying teenager from swiping your seat because they can.

If you're going to be locking the bikes at all, ask the shop to swap the quick release on the seat post for a normal bolt. (And don't make your wife put the rack on hers because you don't want to look dorky You'd be surprised how much more pleasant and practical the bike is if there's a place to carry stuff. Or just wait and buy a new post in the future, it's a $15 - $20 part. Ask the shop if they'll swap it out for you at no charge (a solid post is technically a cheaper item than the suspension one, so they may be willing.). I wouldn't downgrade just to get a solid seatpost, but those suspension posts do get loose over time. Lined tires are preferable (though not a huge deal). It sounds like the Spec's tires have a puncture resistant liner, I can't tell on the Trek. Test ride and see if one shifts/brakes better than the other. The parts are "comparable" but not identical. Performance wise, the biggest difference will be in shifters and brakes. If the Trek's aren't stainless, that's a strike against it. The Specialized lists "stainless" spokes. But a cassette is better, if one has that, it could be a factor. The specs are slightly vague, I can't tell if they have "freewheels" or "cassettes" in the back (probably freewheels). Are they from the same shop? If not, I'd go with the shop you like better, that will make a bigger difference than the bike.

They are very comparable bikes with no major differences, both look good and you should be happy with them.
