this does "appear" to be a rip off, but im not going to make up my mind until some comparisons between other workstations are made (yes a 'dekstop' vs workstation comparison may look the xeons look WAY over-priced, but how many professional users/businesses will get the cheap stuff??

)
i have a question:: why does apple insist on using the xeons for their quad-core machine? they are not loosing any benefits through QPI as there isnt another chip, the loss of ECC memory could be made more 'attractive' if apple put in some nice fast RAM (1600mhz or something?) and it had support for 32/65gb of RAM.
the benefits of using the i7 would be nice, MUCH lower initial cost and MUCH cheaper RAM, the expandability would still be the same. maybe it could be the xMac??
so as i see it.. the only differences between the corei7 and xeons are:
1. RAM, ECC vs Non-ECC (which could possibly be turned on in a corei7 because there is full support for it there, its just "locked")
2. QPI, the xeon allows two chips to communicate much faster and more reliable then the other method..
thats it, i think.. for that anyway
another comparison that would seem important (at least for me) is the differences in the OS + software. in a business situation where they are using Macs for years and years for their production/calculations/etc then of course they would still purchase the latest and greatest Macs, no matter on the costs because 'switching' would cost even more! personal preference would also come into it i guess.
