I remember during the PPC to Intel transition, there were many software companies waiting until the last minute to update their applications. "Just run in Rosetta" they kept saying, until Apple stopped supporting PPC.
Even today we have software companies and IT departments telling users "We support Mac, here are instructions for running our application on a Mac". That "support" was nothing more than steps for booting into Windows.
I'm waiting to see the same companies tell ARM Mac users "just run the iPhone application on the Mac"
