I think the dual cpu models are a different breed, but the sp ones, the low end MP...i think that for most users, they are a lousy value...
for 2,499, you get
$ 300 cpu
$ 150 gpu
$ 125 HDD ?
$ 50 DVD drive ?
$ 75 for 3x1 GB ddr3 ?
$ 75 bucks for mouse, cables, keyboard
So, what does that leave, $1,700 for mobo, case, power supply and image...oh, and profit margin...
Not a great deal, and an even lousier deal if you have been waiting 500+ days for the tech refresh like i did..small bump in cpu, year old $150 GPU and rounding up the HD to a full TB....so much for Moore and other similair theories...
Yesterday, when i speced out the low end MP, added the better GPU and a +400 bump in CPU to get it to 3.2, i was 1k above a loaded i7, not including monitor (yes, the 3.2 and better cpu are faster, not sure why you would get a base MP without a performence bump above the imac in the first place). I just couldnt justify it. If i could justify a multi cpu or 6 core, it would have been an easy decision, but 500 to 2k more for a 4 core CPU (depending on how you count it), just wasnt worth it to me. I will just tech turn my new imac in half the years as i would the MP.
But, everyones mileage might vary. Having the expandability in HDD, upgradeable GPU, PCie cards, etc might be worth it. But from a value proposition, i think its a very small crowd that can make that arguement on a SP MP. And it seems to get smaller every year...in my case, in 1.5 years, it will be far easier for me to cascade to another family member a $2.3k system when the 2012 MP comes out. Yes, even though i didnt buy one yesterday, i still want one, just not at this value! And thats the point, at least for me, it wasnt the Price that bothered me the most (although 3.5k is hardly worth ignorning), its the value. In my mind, they are just such horrible values compared to some of apples other products...i just couldnt get over it. (my issue ! 🙂 )
