I guess nobody uses slide rules any more.

There are still plenty of slide rules made for pilots, printers,
doctors, and so forth. Dozens of makers of them, including:

http://www.concise.co.jp/eng0731/slide.html
http://iwa-slidecharts.com/en/
http://www.perrygraf.com/products.html
etc..

And a whole bunch of us active slide rule users live at:

http://tech.groups.yahoo.com/group/sliderule/

I, for example, design manual flight computers as a hobby for myself,
using SVG to generate the graphics. I also researched and posted the
E-6B's history on Wikipedia, and have written a couple hundred pages
towards a book on the history of all flight whizwheels.

All good news to hear. But I guess Pickett is out of business (?).

Yes, but their entire inventory, which was about to be sold to Mexico
as scrap, was bought by a collector 25 years ago, and is fed out to
others.

Other families, like the Faber-Castells, don't make slide rules any
more, but have hosted collector parties in their castle and given away
valuable samples.

In the International Slide Rule Group I mentioned before, we still
have a custom rule made for us every couple of years or so.

Wow! That's a pretty good way to retire!

I don't understand why they aren't made any more. There are times when
something that's quick, "close enough" in accuracy, and requires no batteries
can be handy.

True, and therefore aviation slide rules are still made and sold in
every pilot shop. New flight computer ideas are still being
patented, thought not nearly in the quantity of decades past.

Here are some examples of makers / sellers of current flight
computers:
