Ditto.

Sure they are, tabs allow you to cycle through windows meaningfully, 
browser > workspace > transcript > process explorer, without getting 
stuck flipping through 15+ browsers.  Once you've found the program you 
want, generally speaking, there's a way to cycle through it's tabs 
quickly to find what you want. Tabs give you context sensitive cycling 
through open things.  Alt + tab through windows, find program, ctrl + 
tab through open things in that program.  Vastly more productive than 
just having everything open a bunch of windows.

More importantly, that's how the rest of the world already works, 
Linux/Windows/Mac all support this; Smalltalk, no no... so busy worried 
about inventing the future it doesn't notice it got left behind.
