In that half year, according to the Sparkle stats, 93.99% of my users have been on 64-bit Intel CPUs. Of the 6% who are not on 64-bit Intel, only 2.72% are using 32-bit Intel, followed by 1.91% on 32-bit PPC and 1.38% on 64-bit PPC (i.e. the G5).
That's very interesting. Not least of all that Sparkle can provide these stats. I didn't know that. I guess today I'm integrating Sparkle and preparing to gather some statistics. I'd very much like to drop 32-bit support in favour of ARC!

I’d caution against putting too much effort into supporting what may well be a statistically insignificant portion of your user base. If you’re porting from GC, port it to ARC, and you’ll save yourself a great deal of time and headaches.
