Comparing 15c ans 35s

I admit that the HP Prime is quickly working its way into my daily workflow. But it galls me to no end that RPN is not fully implemented. I frequently revert to using it in textbook or algebraic mode--and that just makes me feel dirty all over.

Fair comparison. Again the HP Prime is ahead of the 15C. But this thread (your thread) isn't a comparison of the capabilities of the Prime vs. the 15C. Complex support on the 35s is abominable.

Bug 15 is the killer for me. For a calculator without any I/O capabilities, the risk of this bug causing program and data loss makes this calculator too risky for my use. I look at the eBay auctions for 35s's preloaded for PE/FE exams and I think to myself, "I hope the buyers have a plan B at exam time."

Part of the frustration is that these are topics that have been discussed to death since 2007.

Thank you for the rational defense of the 35s. I've re-read the bug list and do agree that some of the items there are simply nitpicking.
