The part of your post that concerns me is the part that says "Addicted to speed.". If this is the case, then the America is definitely not for you...
...that said, if you can overlook the loss of 70 or horseys and you feel like a change of pace, then the America will give you your kicks in a different way. It will do most things asked of it-tour, cruise, commute, etc but will do it with, as you say, soul and a style all of its own. The handling is sweet, the motor willing and the intangible 'feel-good' factor in a league of it's own.
Will you regret getting one? If you decide the lack of power isn't a problem, then the answer is a resounding no...until, of course, you get to see the far superior black Speedmasters!!!
If the carbs trouble you, wait for the '09 models to come out next year-these will be injected.
Reliability: it's an air-cooled, over-engineered, under-stressed, parallel-twinned motor and if you read through the forums, you'll see people who've clocked up beaucoup trouble-free miles on them.
If you do decide to buy and then realise you want more power, there are a few options ranging from improving the breathing (filters/pipes) to big-bore kits and turbos.
And lastly, you get a forum full of nuts to share your experiences with.
As 57 says, above...take a test ride.
