This is going to become more common as more programs copy the Microsoft "Ribbon" style interface.

But the Ribbon was designed particularly for Microsoft Office. Some of the things like icons for Bold, Italic, Underline, etc... are so commonplace and pervasive that MS Office can get away with little icons for these things without really losing comprehension.

But I don't think that the same holds true for other applications.
