Well yes but maybe it's not so expensive if I think about it as a small desktop (and with a touch screen!) that can fit in a pocket and can be carried over between places where I have everything I need to use it. Maybe it's not even so big anymore ("160.8 x 76.6 x 11.1 mm") and so heavy ("Approx. 215 g"). Those data are from the very bottom of https://www.pine64.org/pinephonepro/

If I think about it as a phone it's heavy like a stone (hopefully everybody agrees), too large (probably I'm almost alone on this one) and too expensive.
