41 with modules vs 42 (HP or SM)

[Allen]

If you're not needing the I/O stuff ( wand/card reader/ etc) or enjoy the synthetic programming, The 42s ( or simulators ) are a winner hands down.

In their physical embodiment, the 42S has better display, faster clock speed, easier menu navigation, more memory, etc.. You'd have to spend 3-4X the price of a 42S upgrading a 41CX (CLOCK crystal, double X-MEM, Advantage ROM, IR printer ROM) to even match a basic 42S in some metrics.

I love Thomas Okken's free42. I have it running on an old Amazon Kindle, PC, and smart phone, in addition to my physical units that are still a joy to use.

This is a matter of opinion, but I've never been able to get used to where the multiply/divide/add/subtract keys are on the 41 series. -Also, not sure if Covid was the cause, but I drove all over town looking for "N" batteries for a friend's 41CV- and ended up ordering some from Amazon, but the 42S batteries are still readily available at "normal" pharmacies. I've seen _bay sellers mistake the 1.5V N-cells for their nearly sized 12V counterparts. "display flashed once, sold as parts" ...
