I don't want a Mac Pro. I don't need dual processors nor do I need the expensive ram it requires. I do not need a workstation.Let's assume Apple develops a tower aimed at the market you're describing. The costs wouldn't be too high for development because the tower that's used for the Mac Pro could be used in a slightly altered form. Now, it would come down to guaging the market.
Apple already sells more notebooks than it does desktops; I believe the ratio has come to nearly 2:1 now. So, we already know that the desktop market is gradually shrinking. Mind you, it will probably level off at some point, but it will probably level off at something around 20% of any company's total sales. Knowing this, why would Apple commit the resources to develop a product whose market is gradually being eaten away? This is one nail in the coffin for your tower.
Now, let's assume that Apple would be able to develop the tower and make enough sales off of it in order to pay off sunk costs like design, marketing, production of the first ten thousand units, etc. Would the product continue to sell in numbers great enough to give Apple it's 25%+ profit margin? Since the iMac starts at $1200, and the Mini ends at $800, Apple would have to somehow convince buyers to forgo the built-in display, and cough up more money for a what is essentially a better Mini. Since $1000 seems to be a good in between marker, let's say that's the entry price for one of these towers. How many consumers do you think, aside from yourself, would go into a store, look at a $1000 machine with no moniter, and then at a $1200 machine with everything built-in, and say, "I want the $1000 machine."? There's a major conflict in terms of price points and features. Granted, the $1000 tower would be more powerful than the iMac, but how many average consumers are going to think about this? For the average computer know-nothing, it's easier to buy everything in a single package. This tower only appeals to those who are going to game, or who need a powerful desktop.
Well, I have good news for you. You can get the powerful desktop, it's called a Mac Pro
No PC maker is doing well in desktop sales, esspecially to home users. By far, most desktops that are sold are sold to the business market.
PS: merge your posts next time by double-quoting.
Without knowing Apple's margins on the iMac or Mac mini, any claims concerning profit margins of them compared to a mid priced tower are speculation. My speculation is that when compared to other computer manufactures, on a feature for feature basis, the iMac is often quite competitively priced. This flucuates as time goes on, most probably based on the introduction of newer, higher priced/higher margin cpus and technology, etc. This seems to hold true more for the higher end than the lower end models. In the price range for the iMac, other manufactures are also making their higer margins. Is it 25%+, I contend that it is. It almost has to be for companies like Dell to end up with margins in the 14 - 16% range.
As far as I know the desktop market is not shrinking, it just growing more slowly than the laptop market.
The iMac and Mac mini use more expensive laptop cpus and ram, the mini uses a laptop harddrive. This at the expense of flexibility.
I own an iMac G5 iSight, I like it, but would rather have bought an Apple mid priced tower. Why should I buy an Apple tv? It uses the next generation of wireless, I've no upgrade path. Should I spend more money for an external wireless router, a la Airport? Makes no sense.
With Leopard coming out, I'd like to buy a relatively(relative to external) inexpensive eSata hard drive for Time machine, opps can't do that, no upgrade path, leaving me to buy a relatively expensive external harddrive with either USB 2 or Firewire ports.
I can only hope that Apple doesn't depricate my computer further by using more of the graphics processor for the OS, core image and audio. I could've just bought a newer generation graphics card, but not for the iMac or Mac mini. When Apple abandoned Firewire on the iPods and went exclusively with USB 2, what were the millions of iMac owners to do if they wanted to buy a new iPod. They could buy their new iPod and suffer the hiddiously slow speed of USB 1 transfer speeds, not buy a new iPod, or buy an new computer that cost at the time >$1000. What did all the Windows user have to do, well, they could go out and buy a $30 or less USB 2 card and install it within minutes in their clunky towers.
Will I sell my Apple stock, no. Will I switch to Windows, no. I value the Mac OS more than what advantages there are with other systems. But, how many switchers will give up their monitor to go to an iMac. How many would give up any internal harddrives or optical drives to go to the Mac mini?
IMHO Apple's extraordinary increase in market share for laptops signals an interest in the OS. The languishing of Apple's desktop market share, to me at least, shows a severe lack of interest in their desktop line-up. Maybe I'm all wrong, but this topic has been a recurring theme throughout most all Mac centric bulletin boards for quite some time.
