There is actually a problem with this in that, in the near future, 
scaling will reach a point where the physics breaks down and oxide 
thicknesses are so small that electrons simply (quantum mechanically) 
tunnel through them, and the number of electrons in a memory cell 
capacitor tends to one.  Quite a few sources suggest this will be around 
the end of the decade.

Unless some other way of continuing the speed up process can be found, 
this might have an interesting effect on the rate of software 
"inventions", as many of these aren't really new ideas, but ones that 
would have run too slowly at the time they were first thought of.

Incidentally, Peter Hart's review volunteers that the K3 is effectively 
an SDR. (Also for those not familiar with RadCom, Peter Hart does solid 
technical reviews, however they also have reviewers who are basically 
journalists (the one who did the handie one used to work for a 
commercial ham magazine).  Increasingly the journalist reviews seem to 
be infomercials, as the RSGB shop then (acting as an order taking agent) 
sells the products at a discount.)
