The primary reason is that the newer parts are generally architected to
make completing most tasks simpler. They further up the chain you go, the
less you have to worry about banking and paging, limited flash and ram, and
a derth of peripherals, such as not having an ADC available.

As for obtaining parts, I for example have a rack of 16F1938, 16F1847, and
a handful of PIC24FV parts that I could pack up and ship to you in a couple
of weeks. I'm sure there are others of us out there that would be willing
to pitch in.

I wrote a piece nearly 10 years ago discussing the obselecence issue. It
was targeted to the 16F84. However, it equally applies to the 10 years of
chips that have followed. You can find it here:

http://www.finitesite.com/d3jsys/16F88.html

The basic points are:

1. Does it make development simpler?
2. Does it work in my development environment? As a linux user that
develops from the command line, this is a biggie for me.
3. Is it cost competitive?

When a new family comes out that meets these three criteria, I move up. In
the last 4 years that move was first the 16F1XXX family. Then the PIC24FV
family.=20

So to answer your final question, it's not whether or not the old part can
do the job. It's a question if the newer part can do it better and cheaper
than the old part.
