As I do ~ 40% of my work from Terminal.app, I'm not sure how the introduction of the Mac obsoleted the CLI.

If only Apple would make the Terminal.app user interface not suck donkey balls. How about a way to resize the property window profile title scrolling list width so it doesn't clip every title after the first few characters and make them extremely difficult to identify and edit, and stop wasting so much of the width on a huge useless icon instead of the title? Is it so hard to make the whole dialog resizable? Didn't Apple invent a way to do that a few years back? Oh and maybe a fucking border around the window edge so overlapping windows don't all merge together? And a way to drag a window with only one tab (which collapses to zero tabs) into another window with only one tab to make one window with two tabs? And figure out why emacs gets confused about the screen width/wrapping and corrupts the display? Maybe fix a few critical usability bugs before wasting time on bullshit like transparency and background images?

...Well at least it's not as bad as the XView cmdtool.

Have you tried iTerm?

GUI. I suppose GUI is an entirely new category of pc, but its still a personal computer.

It obsoleted the CLI for 99% of computer users, just like PCs obsoleted minicomputers and mainframes for 99% of server operators.
