iPad, iPhone, and iPod ARE personal computers now. The old personal computers that you refer to are dead (or close to it). The iPad and iPhone are the way of the future..
If you mean the Smartphone, the iPhone has been overtaken by Android.
So, how are they dead again? The PC Desktop/Laptop Market is far from dead.
Dead? PC sales are expected to climb next year, and even higher next year. The Desktop/Laptop PC is far from dead. Far far far far from it.
Why?
You CANNOT get any serious work done on an iPad. You really think enterprise will trade in their dependable, cheap, and extremely productive PC's for a tablet?
Anyone who thinks the Desktop/Laptop will be 100% dead any time soon, just drinks way to much
Things like tablets just Expand the Desktop/Laptop computer. They are not a replacement for it.
Plastic is ugly and tacky and makes it look like a kids toy. The unibody aluminum casing is the best thing that Apple ever designed.
I would disagree.

Apple certainly has the resources to develop a competitive and compatible office suite.
Of course they do, but the problem is, Office has over a billion users, getting that many people/companies to switch to an Apple platform would be...problematic. Plus they have no reason to, Office is made for OSX. And I bet Apple gets a decent chunk of those profits as well.
As for your other comments about Apple over-charging for low quality, I disagree. I remember when Apple over-charged. Apple's prices have come way down and I believe they provide excellent value. Of course, if you fully load a MacBook retina, you'll go for a ride, but I frankly think that the computing power of these products has become so extreme that I am usually disinclined to believe those who "need" to max out their system
Look no further than the Desktop Mac line, all extremely overpriced.
The Laptops? Thats another story, the MBA is fairly priced. The rMBP is fairly priced as well, I would consider a rMBP if they had decent hardware, but they don't
And yes, I need to Max out my systems, the kinda work I do pretty much requires it.
I do believe that Apple delivers excellent quality and support at a reasonable price. Is it the lowest price? No, but the quality is there, and the support is unbeatable, at least if you live close enough to an Apple Store. And of course you get MacOS instead of Windows.
They do offer decent quality, I would never say " high end " though. At least from my prespective, I mean look at the Mac Mini? What a rip.
The Support is very good on Apple, but its also no better than the Support I get from the company that built my Gaming Rig ( I can mail it out and have it back in 2 days if the need be. ), and my Alienware is supported via a local computer shop which is dell certified, so I can take it in there to get anything fixed.
Same with the Apple store, and my iMac 11 has been in there a couple times ( mostly for stupid problems ) and the service has been pretty good. Though I find most of the genius bar to be lacking a genius. And the way they try to sell you stuff you don't want gets annoying, but it is their job. I don't blame them personally.
