This doesn't really seem to be an "Ultimate developer & power user tool" list. It seems to be more of a "this is what I use".

According to you, your ultimate setup for Rails development includes a machine that loads the Rails stack slowly (!), a 24-inch monitor (while you say you'd love a 27-inch), and headphones that sound "ok".

You have an interesting definition of "ultimate".

The title is riffing off of the other two posts I mentioned at the top of my post.

Regardless, all of these lists are personal opinion and limited by resources and current technology. I prefer portability over speed, for example.
