To be fair, it's also priced dramatically lower. It's not fair to compare a current iPhone, priced at more than $1200 on the open market, with the Pine Phone priced at $150. This is where they chose to bring a phone to market and I think it's a smart move. They'll attract a bigger audience and make it easier for people to sim-swap and experiment.
When the distros get good enough, they can price out higher end hardware.
I'm all for having tuxphones but even a $100 Android phone creams the Pine Phone in every aspect regarding performance. The sad truth is until the soc vendors don't start properly supporting a mainline Linux kernel and offer open source drivers we will be stuck with devices that haven't left the "wow this is cool but I wouldn't use is as my only phone" territory.
That $100 Android phone is going to be carrier locked (subsidized by the carrier) and probably an older model where the R&D has already been paid-off, not an all new device. Once the Pine64 has been out for a few years, it's possible its price will drop to similarly competitive levels.
