right
it's a matter of perception.. for one, 'internal expansion' is pretty much a misnomer because as far as i can gather, you're still buying drives and putting them inside a box.. and you're still paying for that box and the capabilities to put hard drives inside of it.. some people want an all-in-one thing- others don't..
i mean, i have a printer and i have a scanner.. sure, i could get them as an all-in-one thing that even faxes and copies too.. but i don't- i'd rather get specialized components that do one thing and do them well.. maybe i'm a bad shopper and spent too much money and have double the cables needed for my printing and scanning needs but so be it..
and yeah, maybe someone with 5 drives inside a macpro will spend more money on storage enclosures with the new mac.. but at the same time, how many empty macpro drive bays (and pci slots) are out there.. we really don't know but i'm willing to bet $ that there are far more empty bays and slots than occupied ones..
if you want more drives- buy more drives.. and pay for an enclosure for those drives.. i don't know what else to say.. i mean, you can't just go to the store right now and buy a hard drive and do something with it.. you have to also pay for something else in order for it to be of any use. nothing has changed in this regard with the new mac.
further, there are advantages of buying a separate enclosure if you're data hungry.. currently, if you buy a computer and cram a bunch of drives inside, you've moreORless tied your storage to that single computer.. what happens if you want to use those drives for another computer? or what happens when you replace your computer? unscrew all of them then rescrew all of them? or just unplug one cord then plug it in to the new or other computer? i'd rather go with the latter.. your storage solution can be viewed as a separate investment and doesn't have to be locked to one box.. it's it's own box.
it's not much different than imac users needing to replace their displays if they want to replace their computers.. where as a macpro user just unplugs their display from the old computer and plugs it into a new one.. you buy your display according to what your needs are.. there is more freedom to customize and build to suit your specific need when peripheral objects aren't tied to an all-in-one deal.. this same idea can be applied to storage as well because storage isn't a computing necessity.. it's an add on and no two people have the same exact needs for their add ons where as an all-in-one package assumes they do and imposes limits by design..
I can access all of my drives and peripherals with other computers already - I have this thing called a network. No TB port or additional cost required.
Putting 6 HDs in my MP cost me $79 (Drive Caddy 2 - not really necessary, but makes the MP neater internally)
How much do you think the TB enclosures would cost for the following:
2x (240Gb) 2.5" SSDs - (OS & Applications)
2x(2TB) 3.5" Hard drives - Data
2x(2TB) 3.5" Hard drives - More Data (iTunes)
4x(2TB) 3.5" Hard Drives - Back ups (Raid Box)
I have been shopping and the enclosures will be around $1,600 dollars (for slower performance, btw).
$79 vs $1,600
Then there are the USB peripherals:
iPhone, iPad, iPod, mouse, keyboard, 2 additional external USB boxes (for less critical data), a scanner, DVD drive (sorry, but I still use physical media) and the occasional camera & thumb drive.
That is another $300 or so for a TB docking station - unless I want to be constantly spinning the nMP around to plug/unplug items repeatedly.
So, unless a miracle occurs and prices on TB enclosures drop through the basement over the next 4 months, I am looking at (cost of nMP) + $1900 to move to the nMP.
I'm not discussing cable hell, because I've been living that dream since I got my first computer back in the 80's. I am used to it and it doesn't bother me.
Then there is that 2nd GPU that will be unused, due to the fact that not a single application I have uses GPU acceleration. Perhaps they will 5 years from now, but they aren't using it today, or tomorrow.
I don't know who Apple thinks the target audience is for the nMP, but as someone who does 3d rendering on a daily basis, I don't appear to be it.
