@"OSX Just Works"
One of the reasons that Apple generate such polemic is because in a limited sense their gear does "just work". But, they are never as fully featured as other gear. One of the ways they generate simple user interfaces is by stripping things out. They are actually very aggressive at this, often preventing third party developers adding it back in. Let me show you some examples:
1st gen iphone. Didn't support MMS or Copy and Paste.
iOS: No desktop widgets, even from third party suppliers.
iOS: No proper multi-tasking.
I could go on, but this short list makes my point. If you don't mind the shortcomings, they can often be great devices. But if you want the features that Apple refuse to provide, you have to look elsewhere. From my personal perspective for example: I won't have an iPod because I'm an audiophile and the quality is too low. Most people don't mind because they listen on the train or similar with lots of background noise, or just aren't audiophiles. I played around with a few generations of iPhones, and can't use the on-screen keyboard. My fingers are like pig's tits and it just doesn't work. I've got a Motorola Droid now because it has a physical keyboard. I can use the physical keyboard, but the onscreen one is virtually unusable for me. If you can use the keyboard on an iPhone, then aside from the slowness of AT&T in the US, they can be good devices.
Finally, Mac OSX can be great if you can live with its shortcomings. If not, it is a disaster.
