One thought that bothers me is as "Developer Rig's" become more and more specialized (i.e. still have command line access, multiple monitors etc.) we will have more challenges getting them. Think about the years we would build our own game rigs because that was the best way to squeeze every drop out of the currently available hardware.

The Mac Pro is a perfect example, I doubt Apple will ever give it serious investment, maybe one more rev next year and that'll be the end of life. As all the various vendors rush towards Tablet and Smart phones etc. we will slowly become the "minority" and end up going back to building our own rigs.

Anyone want to start an Alienware for Developers?
