You're having a laugh, aren't you?
Whatever the merits or faults of GNU and other FOSS groups, and the reasons for them, what you say is ridiculous.
"(Quite why the GNU / FOSS movement *still* can't achieve something Apple managed to pull off with rather fewer resources and a lot less time escapes me, but you don't get to blame Apple for the FOSS community's failings.)"
Rather fewer resources?
Haha.
I don't really know the hard numbers (does anyone?), but I do know marketing is not cheap. And Apple's marketing is everywhere all the time -- I've lost the count of how many times I've seen that stupid iPod nano ad showing its video capabilities ("simulated", as the disclaimer obviously states) on TV last night only, for instance. So I guess it would be safe to assume that Apple spends more money on propaganda in a month than GNU has ever had their hands on for whatever purposes. Same would surely go for other FOSS projects like KDE, *BSDs, etc.
A lot less time?
Well, when you use someone else's free code as the basis of your OS, then I guess it does cut some corners. And anyway, "a lot less time" would be debatable. As I remember hearing, the first version(s) of OS X were quite crappy, and it took Apple some years to get it straightened out. Some might even say they still are trying -- like I feel like doing, every time I use that stupid Mac mini we have here at the lab (the old one we had was the same, so it's not just a bad, er, apple). The thing is quite buggy for a system so highly regarded. But that's propaganda for you.
P.S.: I don't hate Apple, and I think they are probably right in this court case against this particular "company". My girlfriend has a Macbook Pro and is very happy with its workings. Never had a (significant) problem, crashes are quite rare for her machine, and I'm happy I don't ever have to even look at it. What I do hate is the religion people here have, the "free-market" myth (wake up, it's non-existent and impossible) cult, of thinking that companies should be allowed to do whatever they want regardless of any consequences. Just because planned economies are demonstrably bad these people jump to the opposite conclusion with zealot fervor. You know, "drowning kills you, so never touch liquids again and you'll live forever" type of "logic"!
