Personally, I don't see what the obsession with single button Mac mice is about.
I have a two button PC mouse on My computer.
And, as I've mentioned before, most of my hardware didn't come from Apple (my keyboard, mouse, memory, CPU, hard drive, DVD drive, video card, sound card, & USB card all not Apple parts).
And the computer itself was bought as non-functioning surplus on Ebay for $17 plus shipping.
If I had to buy from Apple (at their outrageous prices) it wouldn't have been a consideration.
And btw, regardless of your prejudices, its well made hardware.
I've never liked Steve Jobs or Apple, but I REALLY like MorphOS on a PPC Mac and I'm not apologizing for that AND I don't want to move to X86 any time soon.
