OK, but where's the payback? Look at how popular automatics are today -- the vast majority of people don't value the extra bit of control that manual transmissions, engine controls, etc. might given them. The fact that you can make a diesel today that the average consumer will find as easy to operate to an ICE (and for no more cost but with a bit better efficiency) is what will slowly drive their adoption. (Although these days the big thing is hybrids and all, so I fully expect that diesels won't make up any significant percentage of consumer vehicles in the foreseeable future.)
We had pretty much every printer that was available, as one of the buildings was used to give demos to potential customers (although of course, at time, only a handful were actually networked -- the big copy-machine-sized ones!).
I wrote up a few little toy utility programs for my manager under VM/CMS written in REXX... good times...
