Now I have a voice in my head saying "you were sooo stupid to buy this HP calculator"

[factor]

Is it that bad? The screen resolution is great and from what i heard the speed is what a "modern" calculator should perform.

To be honest, about half year ago after heard about this calculator model and played with the emulator I tried very hard to find one but there isn't any here. I emailed HP and got no response.

If I remembered it correctly, the manufacturer of the core processor of this model was acquired by another company and since then it appears that HP basically gave up this model.
