In the US store it costs 200$ for the original PinePhone and 400$ for the Pro version. The EU store is a little more expensive.
I’m not the person you asked, but I’ve had mine for 2 years.
Pros:
free software and freedom (and with that increased privacy and security)
runs the same software that you can run on desktop as long as it has an ARM build (a lot of Debian packages do) or you compile it yourself - this includes not just apps, but also terminal programs and servers
killswitch to power off the proprietary modem for when you don’t want phone carrier tracking you
like in other modern phones the modem is isolated (here it’s connected over USB)
multiple distros to choose from
multiple desktop environments to choose from
replacable battery
headphone jack
replacement parts available in case you break something
you can boot from the microSD card, so distro hopping is easy
can run Android apps through Waydroid
Cons:
slow - you are running modern software on an old SoC (the Pro version is faster, but still slow compared to modern phones)
not all GNU/Linux apps have a responsive UI that works well on mobile
some old apps might not have touch support
short battery life - the SoC is not very energy efficient. Possible workarounds: get the keyboard addon with builtin battery (but it makes the phone bigger and heavier), carry spare batteries with you, or buy/3D print a bigger case and use a bigger battery
runs hot
GPS isn’t super accurate
audio quality during phone calls isn’t great
the non-pro version might not be able to run a mainline kernel, so you might not be able to install a desktop distro on it
the Pro version should be able to run a mainline kernel, but there might be things that don’t work
experience with GNU/Linux is required
sometimes workarounds are needed - for me, on Mobian stable sometimes the modem or wifi don’t wake up from suspend and I have to reset it with a script (I added it to the apps menu for quick access, but it’s still annoying)
[on original PinePhone] bad camera and the default app can only take pictures - there is a script for recording video, but then there is no preview
I’m not sure if you can use the camera as a webcam in most software
[might depend on the model] video playback is not GPU accelerated, so it makes the CPU hot and drains battery and you might be limited to 1080p@30fps or 720p
you can run a stable distro with old software and old bugs (and sometimes things change very fast) or a less stable one with current software, but then things will sometimes break after update and you will have to fix it (probably more than on desktop)
on Mobian stable (old software) the proximity sensor acts weird during a call and sometimes you can’t see the screen
no Xbox gamepad support in Mobian stable (but Playstation gamepads work)
they keyboard addon isn’t perfect and requires some setup
with the keyboard addon I can’t plug in any USB devices to the phone and I don’t know why - charging works though
[original PinePhone] uses micro SIM standard instead of nano SIM
sometimes there is screen flickering in non-pro version
killswitches could be a bit easier to flip (they are very small)
[on original PinePhone] poor 3D performance (even SuperTuxKart doesn’t run smoothly), WebGL doesn’t seem to work (at least for 3D)
not a lot of RAM, so you can’t run too many apps at once or have too many browser tabs open - you can still run Electron apps, though (just not too many at once)
no push notifications, so if you want to be notified when you get a message in some app, while the phone is suspended, you would have to setup a script to wake the phone up periodically
Edit: I corrected a mistake with the SIM card. I turns out that PinePhone Pro uses nano SIM and it’s only the original PinePhone that uses micro SIM
