In regards to the $8K Mac vs $800 PC, I am sorry but the day I start working on PCs that cheap I might as well get out of this business.
I’ve had numerous PC workstations from Dells, BOXX, SGI (yes SGI!), HP, Compaq, Intergraph (uh oh I’m dating myself) and even the cMP (Mac Pro legacy in BootCamp).
Since 1994, the practice of going cheap with PC workstations went as far as trying to keep that one printer alive for longer than 2 years 😛
Now, of course this was during my heavy CGI days with Maya, Softimage, 3DSMAX and etc….
I use both one being a loaded nMP.
I will still use my trusty BOXX for 3D work, but my nMP will always handle the Adobe updates as oppose to any Windows options.
For some reason everytime Adobe does an update, the PCs tend to throw up for a few weeks before finally settling in.
Just my opinion of course.
