Unfortunately, only their hardware is modern. :( The software is outdated and too limited. I'm annoyed that HP basically shrunk down their calculator team down to two people or so and that nobody is working on a worthy successor to the HP50g. The HP Prime is definitely not a worthy successor. I especially dislike the incongruent mixture of two different calculator engines, and now they've added Python to their own programming language to make it even more confusing.
I guess engineers all use tablets or Wolfram Alpha by now and so they figured there is no market for it.
