Ok.. gotta jump in here...
Boxer engines, along with Inline 6cyls and V12s are naturally balanced motors. Very smooth! I found a great article a long time ago that goes into a fair bit of detail about what motors are balanced and such. I liked it enough, I scraped it from the site, and put it on my server. Her is the link.

And specifically, for the Boxer engine.

The rough idle issue some (including myself) notice, could be a result of rotational mass. The flywheel holds energy, and if its RPM changes, even just a little bit, you'll feel it in your car. Kinda like when you blip the gas, the car shakes.

Just my .02c worth.
