Review: Ex-possesseur d'une HP33C au début des années 80 (finie volée), puis d'une HP 15C qui m'avait duré presque 30 ans avant d'être perdue dans un déménagement, le choix d'une HP s'imposait pour moi. Je ne suis pas déçu avec cette calculatrice, reçue hier. Les fonctions sont complètes (j'aime bien les conversions d'unités). Le catalogue de constantes physiques est un peu gadget, mais pourquoi pas ? L'affichage sur 2 lignes est intéressant pour mieux gérer la pile en notation polonaise. Il devrait aussi permettre à ceux qui s'y mettent juste d'apprendre plus vite et plus simplement. Je n'ai pas testé la programmation, mais je m'en sers beaucoup moins à l'heure des tableurs. J'avais un peu de crainte pour les touches après avoir lu les commentaires mais aucun problème de ce coté là. elles cliquent parfaitement et aucun raté ni doublon. S'il y a vraiment eu un problème il est maintenant corrigé. D'ailleurs, j'ai acheté en même temps une HP 300s+ pôur ma fille au collège et, si les touches sont évidemment de moindre qualité (vu le prix), elles non plus ne posent pas de problème si on les presse normallement. La pochette reçue ne correspond pas à l'illustration mais protège correctement. En conclusion, je suis parfaitement satisfait de mon achat.
Review: Despite having a couple of HP calculator emulations on my iPhone, it somehow isn't the same. My "every day" calculator (HP 42s) was beginning to play up, getting increasingly difficult yo read the display, so time for a new one. In general the HP35s is better in nearly every way – particularly in flexibility and ease of use, and it is AMAZING value – I paid over £100 for my HP42s over 30 years ago! There are only a couple of niggles; conversion from litres to gallons (and back) is in US gallons only. This is mildly irritating as we buy petrol in litres, but then work out mileage in miles per gallon. It isn't a difficult calculation, but having it teasingly built in is annoying. My only other complaint is that I wish it was built to the same standard of HP calculators from the 1970s and 80s, it just feels a bit plasticy. I would happily pay more for better plastics and an olde style soft click of the buttons of yesteryear. As to RPN, it is clearly better, easier, more efficient, more logical and elegant than algebraic entry (as 100% of people who know and use RPN will agree), but for those too timid to dip their toes in the RPN pool, it can work algebraically too.

Come molte altre calcolatrici HP anche questa e' un ottimo prodotto . Consente di fare molti calcoli anche complessi ed e' adatta direi per un uso scientifico . Il display ha poche righe ma ma non si puo' pretendere troppo da una macchina che ha una tastiera molto estesa. Un ottimo acquisto
