My main machine is a 500MHz UltraSPARC II.
The IDE from Sun is NetBeans.
So I tried downloading Sun's IDE (written in Sun's language)
from Sun's website and installing it on Sun hardware running
Sun's operating system with Sun's compilers.
And it didn't work.

Last night I was using Microsoft Visual Studio 2008 on a new
laptop (not mine).  It did nothing to improve my opinion of
IDEs, let's put it that way.

The worst thing that these things hog is screen area.

I'm a fan of Smalltalk, which gets the screen area bit
right.  It's pretty much the only IDE that I do like.  But
they said "oh, machines are faster bigger, so we can make
pretty-print-as-you-type and colourising defaults" and
pretty soon the 1GHz PowerMac I was using was crawling.
Hogs!

The Smalltalk refactoring browser is a fine example of that.

Meyer's LACE referred to the "Language for Assembling Classes
in Eiffel."

As for design errors, there are differences of degree.  The
inconsistencies in the dotted module names "feature" put it
roughly on a level with C's switch() statement.
