I'd say it depends on what you secretly want to do with the bike.
On balance I'd probably suggest getting a hybrid. They have a lot of flexibility; they are great for and arguably offer a more comfortable position for commutes and do work well as road bikes as well, I've knocked out many 50+ rides on mine, so its not as if you are limiting yourself by going down the hybrid road. They can be a bit more robust and forgiving as well - both on themselves and the rider - on less than immaculate road conditions.
Also, if you get a road bike with drops, it may be a bit jarring if it's not something you are used to. Most people who have cycled (even if it was back in their youth) will have used flat bars, so a hybrid will probably be far more natural.
You can always n+1 in the future if your love affair blooms, and have your workhorse hybrid sat alongside your fun roadie in your garage.
On the flip side, go and test ride some. If you are one of the lucky souls who take to drops like a duck to water, and harbour serious dreams of very quickly developing your cycling beyond 12 mile commutes into much longer runs and taking it on much more as a hobby, then you could 'skip' the hybrid and get straight onto a road bike. Although, I'd suggest a hybrid is always a decent option to have in the hanger, even for a dedicated hobby roadie cyclist, so as I said, on balance hybrid first, nice shiny roadie when you feel the need for the +1. But then, thats just me.
