What can a stock 41CX do that a 42S can't?

The 42S has more available RAM than a 41CX with two Extended Memory modules, so you won't need program files, and matrices can do most of what data files can do, including sequential access. And the DM42 has even more RAM, and its own version of Extended Memory in the form of a flash disk (but without the ability to access it programmatically: no SAVEP, GETP, etc.)

Yeah, program files are obviously unnecessary. Data files could be emulated easily enough with single-column matrices. ASCII files might be a little trickier, but I'm not sure if there's any compelling use case for going to the trouble.

Oh right, can't forget alarms. That's something I'm hoping makes it to the DM42, even though it obviously doesn't make sense to support them in the mainstream builds of Free42.
