However, plain interior =/= low quality interior.
And I'm sorry to hear about your mother-in-law's 2004 Camry, but does that mean all of Toyota's products are? I'm sure there are people who've received defective Apple products, and complained about how Apple's QA "isn't up to the quality of years past" (or what about the issue years ago with the iPod batteries, or the first generation iPhone screen problems).
The interior isn't "plain," the interior is of low quality materials.
It isn't defective, it's cheap. It's the same as every other Camry of her model year. It's a cheap product. The plastics are cheap, the doors feel flimsy, the fit and finish are just not up to Toyota (of yesteryear) standards. I've always been a fan of Toyota (though I'm a Honda buyer generally), but there is no doubt that they've cheapened their product over recent years.
Sure, Apple has defective products just like any other company. But you can't put your eyes or your hands on a MacBook Pro, an iMac, a Mac Pro, an iPod, or an iPhone and honestly call it cheap. And there is no comparison, build-wise, between a PowerBook of 10 years ago and a MacBook Pro today. Apple continues to improve the build quality of its products, and invests a lot of development money to do so (i.e. unibody construction process).
How is it not a very good OS? It's stable, far more secure than XP and Vista. Device compatibility hasn't been much of an issue so far. It can run on systems that even Vista had troubles with at times.
My Apple II+ (which still runs) is also stable. Does that make it a very good OS?
Windows has (and always has had) a certain amateurish feel to it that can be hard to explain yet is readily apparent. It's like the bits and pieces were not cut from the same whole but were stitched together from various scraps. Some icons are nicely done, others look like they were cribbed from XP (which they probably were). Some are three-dimensional, others are not. Jaggies continue to abound. Frankly it has a decidedly Linux feel to it, where there was no cohesive design philosophy. And the elements that directly ape OS X are just embarrassing in their obviousness. Seriously, you can't make a recycle bin icon any other way than to recreate the OS X icon and slap a recycle symbol on it? Geez, where is the creativity? It can't be that difficult. Windows Vista/7 tries (poorly) to mimic the colored glass look of OS X (released 8 years ago) at a time when Apple is moving away from it because it's old news. And "Aero" instead of "Aqua?" Sheesh.
These are just cosmetic elements, of course. I have plenty of frustrations with the intuitiveness (or lack thereof) of the Windows OS as well (and I've been a Windows user since 1992).
Sure, there are a number of areas where it's clear that they took the idea from OS X (such as the taskbar redesign and Aero), but if anything people should see that as a good thing for both camps: it means Apple did a tremendous job with their GUI design (so much so, MS wanted to copy it), and at the same time, it improves the computing experience for millions of more people.
Ah, I see. Microsoft copies Apple's work for the benefit of mankind. I get it now. I can see why some argue for Bill Gates' sainthood. Hey, Apple should be flattered, right?
And not "everything" Microsoft produces is "mediocre". Just because you don't like Microsoft or its management doesn't mean you have to discredit everything MS puts out.
I like their mice (sorta) and I like Outlook.
I don't like Steve Jobs at all, but I don't let that sour my viewpoint of Apple.
My viewpoint of Microsoft has been soured by using their crap for 17 years and watching their weasel-ish business practices. And sure, observing their sweat-soaked CEO run around on stage screaming incoherently like a rabid ape doesn't help my opinion of them much either...
