- menu driven (depends on taste, but I find the menus much faster and intuitive than what I have on my TI BAii+pro)
- programmable (to some extent)
- nice feedback to the keys (in fact, the best I have ever encountered on a calculator)
- rpn (I love it, probably like most finance professionals)
- well, let's be honest: it's a nice calc for the early nineties, using the technology of the eighties. This is not the piece of electronics you would expect to get in the year 2013.
- I can confirm that the keyboard does not register key presses at times, as other reviewers have mentioned
- the slight 'barrel' shape makes an impression as if the back cover were too small to fit the keyboard, somewhat spoiling a decent design.
- I would be nice to have at least 2 lines of stack visible or at least an indication which level is currently displayed. I often have a temptation to go back to using my old HP48 because of that.
- Sadly, overall I think that reputation and customer loyalty is not so important to large corporations anymore.
