Same here, but that's more a matter of personal preference for this kind of calculators and the wish to have all those new functionality in comparison to its predecessors. It would be much more reasonable to use a 42S, 32S(II) or a 15C imo as I think finding new bugs is more likely with the 35s. I hope I can estimate the results well enough to catch a new problem.
