Considering 35s acquisition

[Tugdual]

I used to own the original 15C and purchased the recent 15CLE which I finally adopted due to the 100x faster speed than the original one. Yes there is this damned PSE error but for the rest I'm quite happy with it.

I recently purchased the Prime for the sake of having the top modern features such as CAS, graphics, touch screen and much much more. This is a very exciting calculator but I would play with it for experimentations rather than use it on a daily base. Also the size is quite big and I'm concerned I may have it stolen or broken.

I would still like to have a proper modern RPN calculator for my daily (small) calculations, a bit like the 15C but may be with 4 rows (X,Y,Z,T) and more dedicated to engineer work including unit conversions and also integer base conversions. I was considering the 35s as a decent replacement for the 15C considering my tiny spec.

I saw that the calculator had been somehow disappointing due to a few cumbersome bugs and I'm a bit surprised by the very little number of topics related to the 35s on this forum.

So two questions:
- Is the 35s a valid option or a comercial failure?
- Should I consider another option? I don't want to go into too much complexity like the Prime, just need something fairly robust and efficient for common daily use.
