Many many points for paying attention to that one- there are lots of disgruntled owners who didn't know, didn't know to ask, or simply ignored that part.

It takes you 15 min to go 2 miles? After the 1st 3-4 minutes of idling to get up to temp, you will see benefit- the electric side will kick in. So you may see some benefit than you think, but still not all of it.

The 'thermos bottle' keeps coolant warmer for a few hours longer, but not overnight. It helps, but more for the 'parked at the mall for a couple of hours' scenario.

How much other driving do you do? What do you have now? If its small, do you want to upsize to a comfy Camry-sized car/family sedan? Remember, the gas engine in the Camry is still not bad, and you will see the benefit of the hybrid system on anything longer than a few miles- certainly you drive other places as well?

And, petty though it may seem, simply feeling better about what you buy is not bad either. If you can justify the price premium to yourself, its nobody else's business what you do with it.

One last thought- clearly you live in an urban area- can you bike or walk to work even sometimes? That beats any hybrid any day.
