You might think of selecting one program of the Staden package
to make available on a trial basis for Mac and Wintel systems.
That could help you gauge interest. Regarding your porting effort,
a Linux verison might be simplest to do and would get your
package to a larger range of hardware.
Regarding which computer systems are most widely used by sequence
analyzing bioscientists: I don't know, probably no one really knows
these days. My impression though is
that Macintoshes remain the most widely used, and despite recent
problems at Apple computer, Macs remain a very viable system that
users of them find compelling. Wintel systems are catching up somewhat.
Unix is far behind as a commonly used (desktop) system,
though many instititions offer it as a shared-service option. But
if you want to reach the most users, write your software to run on
all these systems (like I do :).
