I feel like I did my best work when I got up from the keyboard and walked around the office, maybe got some cookies, and thought of the big simplifying idea. And sure, I have no problem banging good ideas into a commodity PC running Linux. That is my preference, actually. They are simple and easily replaceable.

Addendum - adding it up, I think I spent about 15 or 20 thousand USD on various Macs from 1984 to 2000. Part of my experience might be "premium fatigue."
