(Oh yeah... I've got 4Tbs that I'd swear it would be quicker to do Full Copies to Empty Drive than wait for defrags. Well, that's why God invented "doing it every day/week", I suppose. That really doesn't take so long then!)
ELBERT, yes, "late in capacity change". And also prices aren't so terrific, either. Back before the Thailand Floods (cough cough), we bought a stack of Hitachi 3Tb 7200s for $139 retail. They've only hit that price recently, and only passing under that mark 'on sale specials'.
I think this high-price for drives AND memory - and heck, notebooks too - are what's stifled the custom sales market. The first generation of i5 notebooks ("4Gb RAM, 500Gb HDD") were on sales specials in the $470 range.
That's what they are now, too. Occasionally, we'll see a low-end name brand (Gateway, cough cough) that will be closer to $400, or refurbs for somewhat less. But these should have followed the market trend of dropping by a $100 or more by this time.
It's not that these are truly "unaffordably high prices" - it's just that they haven't dropped as much, as fast, and customers are saying, "Why spend the same amount when I'm getting minor or perhaps not even noticeably faster performance? And where's the new killer apps? I'm still doing exactly the same productive work I was in 2003. Why get a new computer at all?"
The maintenance of these high prices AND relatively slow increases in services or performance improvements gives consumers the idea: "Sure - stick with XP... why not? Stick with my 2010 notebook - why not?"
Cut the massive HDDs into the $100 range... 16Gb RAM into the $50-80 range... (it IS great to see 1Tb drives in the $50-60 range. Honestly, they can't get much lower.)
