Well, I generally include inability to run microshaft software when I'm trying to figure out how cool a system is. Those that you can get a winders emulator for generally rank above those that run it natively, and those that you can't get an emulator for above that, A.S.O. -- I'm not sure how you'd turn that into a number to be used in a calculation, though. Perhaps that would be going the wrong way -- it would be simple just to find the minimal amount of internal storage required for a "supported" system, in comparison to the space required by the full system, and to subtract from the score based on that number. That would certainly harm more "modern" systems which run microsoft software ;) This "internal storage density" would probably be something like: (<Fixed-Media> + <RAM> + <ROM>)/Meters^3 (where the storage should be represented in some suitably large or small unit) Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '
