Same here.
Flat-4s are part of Porsche's history as well so it's not exactly sacrilege, but I'm not a fan of the idea. Part of my love for Boxsters is their seamless power and acceleration. Neither 4cylinders nor turbos are known for seamless operation. Combine the two and I see a Boxster with a lot of peaks and valleys in the power delivery.
Hopefully I'm wrong.
