Top computer - but Retro

That it is a high quality product is unquestionable. Alone, because I use it for what felt like ten years and he is still working properly. This created not the legendary 48GX due to design defects.

Nevertheless, it must be said that it is old technology.
He is huge and the batteries do not last very long in real use. The display is not bad, but not really arrived in 2013.

Honestly he is considered a legend hp. Solid and safe quality.

But if you really need the features and use every day, then I would use other hardware.
For reckon there are HP excellent small models that allow pleasant working with high-quality keyboards and keep their batteries for a long time.
For functions and work with equations, there are iPad software that is much more efficient faster and more convenient.
And if it really needs to be a little all-rounder handheld, then a nSpire would also be much more powerful solution.
