I do most of my work on PCs, but I can appreciate Apple's innovation when it comes to interface and presentation.
I can't speak to whether it's "old tech" or not - or for that matter who would give a damn if it was or wasn't. All tech that's available for personal/home use is "old tech", isn't it? That's why you can afford it.
But that said, I can tell you that my 63 year-old mother hated the Droid phone I gave her, but loves the hell out of her new iphone and ipad. She's not a fanboy (hopefully for obvious reasons), but she appreciates the engineering and design that went into the interfaces, and she wouldn't be nearly as informed (read: plugged in) if she didn't have those devices.
I'd agree that the marketing is top notch, and there's no arguing that the products sell - but it's not all marketing.
