Dynabook hw cost

Well personally I am very hopeful about this proposal.  I have been thinking
for some time now that it is time to look at a new style of OS, and this
sounds very good indeed.  Do you have funding yet?  When can we expect to
see something we can play with? :)

Let me clarify what I meant since the way I phrased the sentence is ambiguous.
I am not claiming that dynabook software can be built in less than 20KLOC. If
our basic unit of assembly is a line of code, then putting together 20K of
them reliably in a way that millions could use it is indeed a challenge. Just
like Smalltalk/Lisp unburdened programmers from tracking memory allocs/frees,
we need better abstractions and separation of concerns. Instead of 20KLOC,
the problem could be factored into two systems of 5-7K each to make it
tractable.
