As much as I love to see people iterate on the boring old command line, this will never catch on.
1) It's too difficult to remember all the tricks to make it useful, and the cost of memorizing tricks that I saw in the first screencast isn't worth the efficiency it provides.
2) It's too difficult for new users to remember the tricks that are supposedly "better." It's a lot like Python vs. Perl -- Perl is a really smart and clever language, but you can type just a few characters more to write Python and it'll be a lot clearer as to what's going on.
The one exception to all of this is the MySQL stuff I saw. The MySQL prompt has sucked for a long, long time, and building SQL queries is something you do iteratively anyway.
All of the above said, I still think this is pretty neat. But I won't use it.
