I’m still not using anything 64-bit.

Did Marco really say this? All the Intel Macs are using 64bit chips and MacOS X Leopard is fully 64bit…
Not all Intel Macs are 64-bit. The original Core Duo is 32-bit only. Intel re-added 64-bit support with the Core 2 Duo.
And while Leopard has 64-bit libraries, I don’t think any of my applications actually use them yet. Hell, I’ve been using Leopard for less than a week.
