How about Macs?
I use Dell Precision computers for my work. The most demanding software is CAD. The Precision line is the industrial strength desktop. It costs more than the bargain computers but not by that much. I get five years before software has evolved past the capacity of the computer. I also buy a warranty. In five years expect a disk or something to fail, Dell will replace it on site.
My architect clients do like the Macs. Don't understand them. They cost more than the Dell Precisions. They need a windows card to run PC software. They have to switch operating systems a few times a day. All this requires more system software to run their pigs of machines.
I don't see an Apple takeover.
I thought Autodesk had most of their software running natively in OS X. I saw a demonstration of Autocad and Maya, I thought it was native. Is that not the case?
