Lets talk about our dream phone!

Here's what mine would be...

Screen: 1440p AMOLED highly saturated screen.
CPU: Snapdragon 845 (Or whatever is on top)
RAM: 4-6 GB
Storage: 16 GB internal OS reserved storage for the OS only but on the side would have 2 slots with the same locking mechanism as the sim tray to hold 2 hot swapable storage or battery modules.
OS: A modular version of stock android (By modular i mean a version of stock android that is designed to be installed on any device)
Speaker: Dual front facing stereo
Ports: 2 usb-c ports on the bottom.

Special features: A portable desktop experience that when plugged into a monitor would give a chromeOS style experience with the phone acting as a touchpad.

As my apt renovation is nearly completed it's time to get all the cool toys. And that's where I need your ideas :)

what should I get? What techie-stuff would you think is worth considering?

I for one have wet dreams about vacuuming robots. Not a roomba ofc [bcz it ties to Apple], smth else. I get that an opensource robot would be a pipe dream, but I'd love smth I could control via bash scripts [prolly via lan] at least. Some api would be nice :) . Any advices here? Cleaning quality should be way above 'okay'.
