How much has RPN/RPL spoiled you?

[Tugdual]

For a very long time I've been using a 15C and nothing else. I actually did my high studies with a 15C and I totally knew all features (except Brouhaha's synthetics ).
RPN became a second nature and with the excellent keyboard I was extremely fast (reason why I don't believe in phones to replace calculators).
A few years ago I decided to have a look on more recent features such as CAS and I bought a Prime. Was pretty disappointed for many reasons: RPN had almost disappeared, CAS was not impressive and Basic totally inefficient for a handled machine (Prime resembles to a computer, except that computers are much better than a Prime). I then had a 15CLE when it was sold for an acceptable price when it was released. Nothing new of course apart from speed and quick battery depletion.
I moved on 35s as a cheap every day calculator and, to my surprise, I found it as good as the 15C, some aspects even better but here again, no dramatic change in experience.
I finally acquired a 48G that I really found very exciting but slow and screen difficult to read. I then discovered that the 50g was pretty much the same as 48G but a bit better (despite plastic case and keyboard). This is now the machine I use the more. The RPL is in my opinion totally aligned with RPN concepts and handled machine coding approach. Better than keystrokes coding much more adapted than basic. I also love the Fx keys, the VAR, the MES solver, easy (compared to the Prime) unit of measurement, easy (same comment) base, the infinite stack. I don't care much about graphics and I stick on userRPL, I'm not a big fan of cryptic coding, calculator has to be simple and straightforward. This machine is a monster not that difficult to tame and very good for a large spectrum of operations, from simple to complex. The 50g is definitely a breakthrough after the 15C and 35s. BTW for fun, I took my original 15C user guide and started the exercises with the 50G. So easy... that is an interesting way to measure progress.
