Is the HP 50g the last RPN calculator?

[ijabbott]

It all hinges on what Eddie means by "last [...] produced". It could mean any of:

1. the last model with feature X introduced into production;
2. the last model with feature X introduced into production that remains in production; or
3. the model(s) with feature X that remain in production, if any, otherwise the last model(s) with feature X to cease production.
   

Also, do reboots such as HP-12C Platinum count as a new model?
