The thing about it is that you appear to be using block-based APIs already, which means you already require at least 10.6, which means that you’re already Intel-only and have no PPC users, so if your user base is like mine, you’ll lose only 2.72% of your userbase by dropping 32-bit. And honestly, your numbers probably *are* pretty close to mine. 32-bit Intel Macs are pretty rare. The most common are the original white/black MacBooks, which were only in production for about six months in 2006, since Apple switched to 64-bit processors almost immediately after they switched to Intel.
