Here's a quick summary to support my claim (not exactly the same specs but very close)...
Mini Desktops:
Dell Zino HD: Starts at $249
Mac Mini: Starts at $699
wimpy 1.6GHz AMD single-core vs half-decent Intel 2.4GHz dual-core, worse graphics, and worse HDD. Similar RAM. Yes, the Mini is still more expensive. Apple will always be more than Dell.
Yes, Apple is stupid to use Intel on low-end machines. Though it might help power consumption ... I'm not sure.
All-in-ones:
Dell Studio 19 All in One: Starts at $399
iMac: Starts at $1199
Bulldust. The $399 one is nothing like the same specs. The $699 Dell has similar guts to the $1199 iMac, and the screen is a crappy 18 inch, not a half-decent 21.
Yes, the Mac is overpriced. But nowhere near as much as you are claiming.
A better comparism would be to the 79,800 yen Lenovo C305 All-In-One Desktop PC. It's about $870 US.
Low-end laptop:
Dell Inspiron 15: Starts at $399
MacBook: Starts at $999
A Dell Inspiron 14 with a slower processor, Intel graphics (yuck) but more RAM and HDD is $649.99.
High-end laptop:
Dell Studio 17: Starts at $749
MacBook Pro 17: Starts at $2299
A Core i5 starts at $849.9.
OK, I'll only defend the MacBook Pro 17 if you need the battery.
Mobile Phone:
Dell: Starts at FREE
Apple: Starts at $99
No idea what either costs without a plan.
MP3 Player 8GB:
Dell/SanDisk: $59
Apple: $149
iPod Nano has a nice little video camera. On the other hand, the SanDisk draws especial attention to it's "fashionable clip" for the "fashion conscious".
Quad Core Workstation:
Dell T3500: Starts at $1239
Mac Pro: Starts at $2499
Dell T3500 starts off dual-core, with much worse specs. Except the GPU ... Mac Pro needs an update.
So actually, the Mac Pro has the lowest difference at double the price of any other product category Apple makes where the difference can be 3x or more. In fact, if Apple priced the Mac Pro like they do their other products, the entry level quad would be $3600 or so.
Again, this is not news, nor appologetic, it is how Apple positions themselves in the market and you either see the value or you buy something else.
I'd call most Apple gear about 40% overpriced, when you really compare Apples to ... Apples.
You haven't really tried to compare Apple gear to equivalent products. You are definitely leaning towards comparing Apple hardware to cheaper parts ... why bother?
