Ya, it's true, none of those features are available on the ST. They are convenient, of course, but I think the driving experience in the ST will make up for the lack of some features.
We should be getting EPA ratings sometime this month. I'm hoping somewhere around 24/34. It'll definitely be lower than the Titanium (this is pumping out 250hp, after all).
And I'm pretty sure you've mentioned all the trade-offs. I can't think of any other missing features.
