Because this was an example and if you want to do anything interesting it's
almost never the case that there is already something prefab'ed. The example
can be extended to any point you want - including business apps. If you
don't know what I mean then check out www.nakedobjects.org (and if you read
the book you will find that eToys are prominently featured in it ... and now
guess why).

Same thing - or else I could just say "IraqCrisis new solve" in Squeak ;-)
Someone has to make these things first. If it isn't a button, then it's
something else. My point was illustrating the vast advantages of the
techniques employed in eToys both in terms of usability as well as
efficiency. But these advantages don't come out of the blue sky - they need
support on the system level and that's why I am so opposed to this backward
oriented way of doing things. But, *sigh*, if all you know is a hammer...

No - you are *entirely* missing the point. The point was usability and
efficiency. Shown in a simple enough example that one can actually recreate
and measure it. We have plenty of other examples - just check out a few of
the kids projects and see if you can get any faster and more robust by
hacking it in the browser. I doubt it.
