i've been watching you spout your ignorance of Macs on this thread for some time... this one is totally absurd. Please show me the $800 Dells and HP that are workstation class machines with Intel® Xeon™ class processors that have Error Correcting Memory DDR3 memory? On the contrary, when you configure either a Dell or a HP to the same specs, the Apple Mac Pro is usually either competitive in LOWER in price.
Here are both the Mac Pro and the Dell Workstations matched as best as possible... The Mac had an upgraded hard drive to 1TB and added 3yr warranty.
The Dell Precision T7500 had the processor matched to the MacPro's, the HD upgraded to 1TB, the OS upgraded to 64bit, Memory to 3GBs:
Gee, Editor, the Dell is $169 MORE expensive than the MacPro... and still doesn't come with the suite of excellent software that comes free with the MacPro... or the excellently engineered aircraft aluminum case, without cabling anywhere in it, that is completely EPEAT GOLD rated... and the Apple MacPro is available TODAY... as opposed to having to wait until May 5th for the Dell to be built and shipped.
Now, Would you care to repeat that absurd ignorant claims about $800 dollar equivalents????
