Apple was selling 1500$ towers, but not for long. They were just NOT selling well. Sorry, you're in the minority.
That was a time and place and state of computing and hardware availability that differs considerably from today. I don't agree with your point at all. And as for being in the minority.... so are Mac Pro buyers. And so are Mac mini buyers... do you propose dropping all lines but MacBooks and iMacs?
As its has been said earlier in this thread, Apple doesn't want "I'll make it myself" kind of customers - people who build their own PCs, or upgrade them from inside-out. Its just not the target market of Apple.
Not valid either... Pro and mini buyers are required to make plenty of choices to make to customize and round out their systems.
And those who dont like the display, should either get a Mac Pro if they REALLY need a good display and cant stand the glossy screen of 24" iMac, or reevaluate their need for "good display" because those cost a lot of money, and if you can't afford it do you really NEED it?
You're telling us that we should do this because you say so? Alrighty then! ;-) Rediculous.
I'm a professional photographer and studio owner. I don't create games or do video editing on my computers. I use Photoshop and various other graphics and general use programs all day long. On multiple machines. I DON'T need MacPros to do this. But I DO need very good, even, accurate displays!!! This can be done for a LOT less than even the cheapest MacPro.
I have paired a MacBook 2.2 GHz with 4 GB of RAM and (upgraded) a 250 MB Hitachi internal hard drive with an HP LP2465 display (24" wide screen with S-PVA panel technology) and have a great mid-power set-up for around $1900. It's really versatile too because the brain doubles as a laptop when I'm away from the desk.
If the MacBook were switched out for an upcoming MINI model with 2.4 GHz or 2.6 GHz C2D with 4 GB of RAM selling for, perhaps $1000, it would be even faster and probably run around $1600 TOTAL. This particular monitor, a $600 S-PVA HP 24" display, is a superb graphics monitor with accurate colors, matte screen surface, no brightness gradient, no light leakage of any consequence at all, and a nice wide viewing angle.
TO pair this HP display with the least expensive MacPro would run $2900. Let's see how happy you would be having to write a check for four of those $2900 systems vs. four $1600 systems which perform quite well for a lot less money! ($5200 savings!) If you don't need all the expansion slots and customization capability as the Pro offers, then a mid-line, good performance MINI paired with a good monitor can provide superb professional service for MUCH less money. And I know there are a LOT of us who want that! (And in another month or so, I think we're going to GET that MINI!!!)
Please don't presume to tell me what I need or don't need to buy or spend to get what I need. I know what I need and what it can be had for.
A Mac Pro and Cinema Display is a great but very expensive and often unnecessary option for many graphics professionals, but there are other very nice Macintosh options to be had which are nearly as effective for professional graphics work for a lot less money.
If you had to buy four $2900 MacPro workstations vs. four $1600 MacMini workstations for photoshop editing in your portrait photography studio, you would understand all of this quite readily! Your perspective is limited.
